In the wake of the U.S. military departure from Iraq and in the midst of Iran’s continued defiance of the international community over its nuclear program, is a new security arrangement for the Gulf in order? If so, is the Gulf Cooperation Council (GCC) capable of such a task, or should other institutions be considered?

In the Saban Center’s newest Middle East Memo, Security in the Persian Gulf: New Frameworks for the Twenty-First Century, Saban Center Senior Fellow Kenneth Pollack examines the possibility of developing a new security architecture for the region.

Pollack analyzes security arrangements in other parts of the world and focuses on two options:  expanding the GCC and turning it into a formal military alliance and creating an arrangement modeled on the Commission on Security and Cooperation in Europe. In weighing each option, Pollack finds that the latter can better furnish a path toward peace and security.

• Security in the Persian Gulf: New Frameworks for the Twenty-First Century

With violent protests following the second anniversary of the Egyptian revolution, and calls for a new unified government amid dire comments about the stability of Egypt, the world’s attention is again on President Morsi and his country. This follows a tumultuous period last month, when Egyptians went to the polls and ratified a new constitution. The document, criticized as hurried, incomplete, and lacking in consensus is enormously contentious.

In the Saban Center’s newest Middle East Memo, The View From a Distance: Egypt’s Contentious New Constitution, nonresident fellow Mirette F. Mabrouk gives a broad overview of the new constitution, and provides context and analysis for specific sections.

Mabrouk outlines several ways in which, she argues, the document is shaky on the protection of freedoms and rights, particularly those of women, some religious minorities and minors. Mabrouk also encourages analysts to stop viewing this situation as an Islamist/ secular divide, arguing that idea is too simplistic, and lacks the context for greater understanding of Egypt’s domestic politics.

The crisis in Syria continues with no end in sight, and in the Saban Center's latest Middle East Memo, Breaking the Stalemate: The Military Dynamics of the Syrian Civil War and Options for Limited U.S. Intervention, Saban Center Senior Fellow Kenneth Pollack argues that until there is a breakthrough on the battlefield, there will be no breakthroughs at the negotiating table.

In his paper, Pollack lays out the military advantages and disadvantages of both the opposition and the regime's forces, and looks at how different opportunities for U.S. intervention can affect those critical dynamics. This analysis provides a much-needed counterpoint to the debate over the possible cost of U.S. options in Syria with an analysis of their likely impact on the conflict.

Highlights include:

• The strengths and weaknesses of the opposition, including: greater numbers, a history of deprivation of political power, the aid of Islamist militias affiliated with the Muslim Brotherhood and Salafist groups, and support from Arab and Western countries.
   
• The strengths and weaknesses of the regime, including: motivation to defend against a determined majority, a geographic advantage, the remnants of the Syrian armed forces, help of foreign contingents like Hizballah, and the support of foreign countries like Iran and reportedly Russia and China.
   
• Options for U.S. interventions to break the stalemate, including:

  • Training and equipping the opposition.
  • Stopping the resupply of the regime in order to diminish its ability to generate firepower.
  • Attacking regime infrastructure targets, such as military bases, power-generation plants and transportation choke points like bridges.
  • Establishing and maintaining a no-fly zone.
  • Engaging in a tactical air campaign against regime ground forces.

This summer, the world has watched as an al Qaeda offshoot, the Islamic State group, launched a militant offensive into Iraq, seizing large swaths of land. This Center for Middle East Policy’s Middle East Memo, Kurdistan Rising: To Acknowledge or Ignore the Unraveling of Iraq, examines how the fall of Iraq’s key city of Mosul has changed matters for Kurds in Iraq, and the necessity for American policymakers to take stock of the reality of the Kurdistan Region in this “post-Mosul” world.

Highlights: 

• A look at the Kurds of Iraq, their history and how the United States has largely spurned a partnership with them. Having been autonomous in Iraq since 1991, the Kurds heeded the aspirations of the United States in 2003 to assist in the removal of the Baath regime of Saddam Hussein, and played by the rules of the game established in the post-2003 period, albeit unwillingly at times. However, they have consistently refused to follow a path that would result in relinquishing the powers they enjoy. They have even taken steps to extend their autonomy to the point of having economic sovereignty within a federal Iraq, thus bringing them into serious dispute with Baghdad and the government of Nouri al-Maliki and earning the rebuke of the United States.

• An examination of how, since 2011, failed U.S. and European policies aimed at healing Iraq’s sectarian and ethnic fissures have contributed to the current situation. By so strongly embracing the concept of Iraq’s integrity as crucial to American interests in the region, key allies and partners have been marginalized along the way.

• Policy recommendations for the United States and its western allies, given that the Kurdistan region now stands on the threshold of restructuring Iraq according to its federal or confederal design, or exercising its full right to self-determination and seceding from Iraq. By ignoring the realities of Kurdish strength in Iraq, U.S. and European powers run the risk of losing influence in the only part of Iraq that can be called a success story, and antagonizing what could be a key ally in an increasingly unpredictable Middle East.

• Kurdistan Rising: To Acknowledge or Ignore the Unraveling of Iraq

A fair assessment of the budget deal signed by President Obama last week would allow for only at most two cheers. Its biggest achievement is raising the debt limit by enough to last until 2017, thereby at least temporarily eliminating the threat to the nation's credit worthiness. The deal also provides funding levels above the Spartan caps established by the 2011 Budget Control Act so that both domestic discretionary spending and military spending can avoid reductions against a baseline that was already low by historical standards. In addition, the deal avoids a cut in benefits in the Social Security Disability Insurance (SSDI) program that was about to have its trust account run dry, as well as a big increase in payments by a significant minority of Medicare beneficiaries.

That's a lot of good policy, achieved despite the partisanship that has been so characteristic of budget negotiations in recent years. So what's not to like? Two shortcomings of the deal are especially notable. The first is that the solution to the pending SSDI shortfall is disappointing. It would be hard to support the imposition of reduced benefits on recipients of a government insurance program for the disabled, but Congress has known for some years that SSDI was running out of money. Congress should have been working on solutions that involved less spending or more revenue, or perhaps both. Instead, the reforms that Congress passed provided a very minor adjustment in the way both initial and continuing eligibility are determined and ignored more basic reforms. A non-partisan group assembled by former House members Jim McCrery and Earl Pomeroy under the auspices of the Committee for a Responsible Federal Budget (CRFB) produced a host of proposals that would address the underlying problems of the SSDI program such as how to emphasize work to control the rising caseload, but they were virtually ignored. Taking the easy way out, Congress transferred nearly $120 billion in funds from the Social Security Trust Fund into the SSDI Trust Fund. Unfortunately, this action will preserve the SSDI Trust Fund only until 2021 or 2022, at which time it will likely be back in the perilous situation it was in until this temporary fix was put in place.

The second problem is that the lubricant Congress used to enact the deal was money it doesn't have. Thus, according to CRFB, all the spending in the deal cost $154 billion but the offsets in the bill amounted to only $78 billion. Thus, the true net cost of the bill, excluding budget gimmicks, was $76 billion. As always, the money will be obtained by additional borrowing, thereby increasing the nation's debt.

Increasing the nation's debt is the most important shortcoming of the bill. Due to improvements in the economy coupled with spending cuts and revenue increases achieved by previous budget deals reached since publication of the Simpson-Bowles Commission report in 2010, the fiscal outlook for the nation has improved. But the long-term debt problem has not been solved. The Center on Budget and Policy Priorities, based on figures from the Congressional Budget Office (CBO), projects that the ratio of the national debt to GDP will fall slightly from its current 74 percent to 73 percent by 2017. However, the ratio will then rise to 92 percent by 2040. This projection contrasts with the Center's 2010 projection in which the debt-to-GDP ratio increased by more than 200 percent.

Granted, this is good news. But not so fast. The assumptions built into the projections are likely to be too optimistic. The CRFB projects that under a more reasonable set of assumptions, the debt will rise to over 150 percent of GDP by 2040. As CRFB argues, the debt path under these more reasonable assumptions is, though improved, nonetheless "unsustainable."

Equally important, the big picture on the nation's budget shows that future spending increases in Social Security, Medicare and other health programs, and net interest will eat up all future increases in revenue. CBO projects that compared to average spending in these three budget categories between 1965 and 2014, spending as a percentage of GDP by 2040 on Social Security will increase by 55 percent, on federal health programs by 220 percent, and on interest on the debt by well over 100 percent. As a result, spending on everything else will decline by around 40 percent. No wonder a recent report from the Urban Institute shows that the share of federal spending on children has already begun to decline and will fall by nearly 30 percent between 2010 and 2024.

Despite the modest achievements of the latest budget deal, long-term budget prospects continue to look bleak and present spending priorities still emphasize programs for the elderly and interest on the debt while squeezing other programs, including those for children. Perhaps two cheers for the deal is one too many.

Government spending on the elderly continues to climb.  Fueled by rapid growth in the number of Americans over age 65 and increased spending on benefits per person, public expenditures devoted to the elderly continue to edge up. A crucial question for future policy making is whether rising outlays on programs for the aged will squeeze out spending on programs for children, especially investments in their schooling. Many pessimists think this outcome is inevitable, and they urge us to reduce government commitments to the elderly to make room for spending on the young.

Federal spending is especially concentrated on the elderly. The Urban Institute publishes annual estimates of federal outlays on children and adults over 65. The estimates inevitably show a huge imbalance in spending on the two groups. In 2011, federal spending for the elderly amounted to almost $28,000 per person over 65.  In the same year, per capita spending on Americans under 19 amounted to just $4,900 per person. This means aged Americans received $5.72 in federal spending for every $1.00 received by a child 18 or younger.

The Urban Institute’s latest estimates show that federal spending on youngsters has trended down in recent years.  After reaching a peak of about $500 billion in 2010, expenditures on children fell 7 percent by 2012, and they have remained unchanged since then.

Future prospects are not encouraging. Urban Institute analysts predict that from 2014 to 2025, only 2 percent of federal spending growth will go to children. Almost 60 percent will be swallowed up by additional outlays on Social Security, Medicare, and Medicaid. Spending on many federal programs that provide benefits to children are financed out of discretionary programs. In contrast, big public programs for the aged seem to run on automatic pilot, with spending linked to changes in the cost of living and the size of the population past 65. Spending on most domestic discretionary programs is expected to be severely constrained as a result of Congressionally imposed budget caps. This is bad news for many federal programs targeted on children.

Focusing solely on federal government spending gives a misleading picture, however. While federal spending is heavily concentrated on the elderly, state and local spending tilts toward programs that help children, notably, through public school budgets.  Whereas aged Americans receive $5.72 in federal spending for each $1.00 received by someone under 19, those under 19 receive $10.11 in state and local spending for each $1.00 received by someone who is 65 or older. To be sure, total federal spending is considerably greater than that of state and local governments, but the imbalance of public spending on the young and the old is less extreme than federal budget statistics suggest.

Government spending on the aged is high because legislators (and voters) decided to establish government-backed pensions—through Social Security—in the 1930s and government-guaranteed health insurance for the elderly—through Medicare—in the 1960s.  In view of the overwhelming and enduring popularity of these two programs, most voters appear to think this was a sensible choice.  One implication of the policies is that Americans past 65 derive a sizable percentage of their retirement income, and an even bigger share of their health care, from public budgets.

The nation has not made an equivalent commitment to support the incomes or guarantee the health insurance of Americans under 65, except in special circumstances.  Those circumstances include temporary unemployment, a permanent work disability, and low household income.  Families headed by someone under 65 are expected to derive their support mainly from their jobs and from their own savings.  If non-aged families prosper, government spending on them falls.  If instead breadwinners become disabled or lose their jobs, government spending will increase as a result of higher disability payments, unemployment and food stamp benefits, and public assistance rolls.

Nearly all children are raised in families headed by someone under 65.  The government benefits they receive, except for free public schooling, increase in bad times and should decline when the unemployment rate falls.  The Urban Institute’s numbers are instructive.  Between 2007 and 2011, real federal spending on children increased 27 percent, or more than 6 percent a year, as the unemployment rate soared in the Great Recession. Federal spending on children then fell as unemployment—and outlays on government transfer payments—shrank.  For many categories of public spending on children, we cannot assume that lower spending signals a weaker commitment to children’s well-being. Instead it may signal a healthier private economy, a lower unemployment rate, and faster improvement in breadwinner incomes.

Of course, some components of government spending on children do not automatically rise in a slumping economy or shrink when breadwinners’ earnings improve.  Public investments in children’s preschool and K-12 education should be adjusted to reflect the needs of children for compensatory instruction and the expected payoff of added investment in schooling.  Statistics on public school budgets show that spending per pupil has increased considerably faster than inflation and faster than GDP per person over the past seven decades (see Chart 1). Whether spending has increased as fast as warranted is debatable, but rising government spending on the aged has not caused per-pupil spending on K-12 schools to shrink.

Government spending on children’s health has also increased over time as public insurance for children has been expanded.  In 2014 just 6 percent of Americans under age 19 lacked health insurance for the entire year.  The only age group with higher health insurance coverage was the population past 65, which is covered by Medicare (see Chart 2).  The main explanation for rising insurance coverage among children is that federal and state health insurance programs have been expanded to cover most low-income children.  Insurance coverage of children can and should be improved, but a sizeable expansion of public insurance has occurred despite the increase in public spending on the elderly.

The presumption that rising outlays on programs for Americans past 65 must come at the expense of spending on children rests on the unstated assumption that voters will zealously defend programs for the aged while tolerating cuts in programs that fund education, income protection, and health coverage for the young.  The trend toward higher public spending on the elderly has been underway for at least five decades, but the predicted cuts in spending on the young have yet to materialize.

Social Security faces a financial shortfall. If Congress does nothing about it, current projections indicate that benefits will be cut automatically by 21 percent in 2034. Congress could close the gap by raising revenues, lowering benefits, or doing some of both. If benefits seem generous, Congress is likely to lean toward benefit cuts more than revenue increases. If they seem stingy, then the reverse.

Given the split between the two parties on whether to cut benefits or to raise them, evidence on the adequacy of benefits is central to this key policy debate. Those perceptions will help determine whether Social Security continues to provide basic retirement income for workers with comparatively low earnings histories and a foundation of retirement income for most others or it will become just a minimal safety-net backstop against extreme destitution?

Down-in-the-weeds disagreements among analysts often seem too arcane for anyone other than specialists. But sometimes they are too important to ignore. A current debate about the adequacy of Social Security benefits is an example.

The not-so-simple question is this: are Social Security benefits ‘generous’ or ‘stingy’? To answer this question, people long looked to the Office of the Social Security Actuary. For many years that office published estimates of something called the ‘replacement rate’—that is, how high are benefits paid to retirees and the disabled relative what they earned during their working years. A 2014 retiree with median earnings had average lifetime earnings of about $46,000. That worker qualified for a benefit at age 66 of about $19,000, a replacement rate of about 41%. Replacement rates vary with earnings. Dollar benefits rise with earnings, but they rise less than proportionately. As a result, replacement rates of low earners are higher than replacement rates of high earners.

As you might suppose, there are many ways in which to compute such ‘replacement rates. Because of analytical disputes on which method is best, the Social Security trustees in 2014 decided to stop including replacement rate estimates in their annual reports.

In December 2015, the Congressional Budget Office (CBO) offered what it considered a better measure of the generosity of Social Security. It estimated that replacement rates for middle income recipients were about 60%–dramatically higher than the 41% that the Social Security Trustees had estimated.

The gap between the estimates of CBO and those of Social Security is even larger than it seems. To see why, one needs to recognize that to sustain living standards retirees on average need only about 75% to 80% as much income as they did when working. Retirees need less income because they are spared some work-related expenses, such as transportation to and from work. Those are only average of course; some need more, some less.

If one believed the SSA actuaries, Social Security provides median earners barely more than half of what they need to be as well off as they were when working. Benefit cuts from that modest level would threaten the well-being for the majority of retirees who are entirely or mostly dependent on Social Security benefits—and especially for those with large medical expenses uncovered by Medicare.

On the other hand, if one accepted CBO’s estimates, Social Security provids more than three-quarters of the retirement income target. Against that baseline, benefit cuts would still sting, but they would pose less of a threat, and not much of a threat at all for most retirees who have some income from private pensions or personal savings.

When the CBO estimates came out, conservative commentators welcomed the findings and cited CBO’s well-established and well-earned reputation for objectivity. They correctly noted that many retirees have additional income from private pensions, 401ks, or other personal savings, and asserted that there was no general retirement income shortage. By inference, cutting benefits a bit to help close the long-term funding gap would be no big deal. Social Security advocates were put on the defensive, hard-pressed to challenge the estimates of the widely-respected Congressional Budget Office.

But earlier this year, CBO acknowledged that it had made mistakes in its Decameter estimates and revised them. The new CBO estimate put the replacement rate for middle-level earners at around 42%, almost the same as the estimate of the Social Security actuaries, not the much higher level that had sent ripples through the policy community. One conservative analyst, Andrew Biggs, who had trumpeted the initial CBO finding in The Wall Street Journal, promptly and honorably retracted his article.

Two aspects of this green-eyeshade kerfuffle stand out. The first is that policy debates often depend on obscure technical analyses that are, in turn, remarkably sensitive to ‘black-box’ methods to which few or no outsiders have ready access. The second is that CBO burnished its reputation for honesty by owning up to its own mistakes — in this case, a whopping overestimate of a key number. Such candor is all too rare; it merits notice and praise.

But there is a broader lesson as well. Technical issues of comparable complexity surround numerous current political disputes. Is Bernie Sanders’ single-payer plan affordable? Will Marco Rubio’s tax plan cause deficits to balloon? To vote rationally, people must struggle to see through the rhetorical chaff that surrounds candidates’ favorite claims. There is, alas, no substitute for paying close attention to the data, even if they are ‘down in the weeds.’

Researchers have long known that the rich live longer than the poor. Evidence now suggests that the life expectancy gap is increasing, at least here the United States, which raises troubling questions about the fairness of current efforts to protect Social Security.

There's nothing particularly mysterious about the life expectancy gap. People in ill health, who are at risk of dying relatively young, face limits on the kind and amount of work they can do. By contrast, the rich can afford to live in better and safer neighborhoods, can eat more nutritious diets and can obtain access to first-rate healthcare. People who have higher incomes, moreover, tend to have more schooling, which means they may also have better information about the benefits of exercise and good diet.

Although none of the above should come as a surprise, it's still disturbing that, just as income inequality is growing, so is life-span inequality. Over the last three decades, Americans with a high perch in the income distribution have enjoyed outsized gains.

Using two large-scale surveys, my Brookings colleagues and I calculated the average mid-career earnings of each interviewed family; then we estimated the statistical relationship between respondents' age at death and their incomes when they were in their 40s. We found a startling spreading out of mortality differences between older people at the top and bottom of the income distribution.

For example, we estimated that a woman who turned 50 in 1970 and whose mid-career income placed her in the bottom one-tenth of earners had a life expectancy of about 80.4. A woman born in the same year but with income in the top tenth of earners had a life expectancy of 84.1. The gap in life expectancy was about 3½ years. For women who reached age 50 two decades later, in 1990, we found no improvement at all in the life expectancy of low earners. Among women in the top tenth of earners, however, life expectancy rose 6.4 years, from 84.1 to 90.5. In those two decades, the gap in life expectancy between women in the bottom tenth and the top tenth of earners increased from a little over 3½ years to more than 10 years.

Our findings for men were similar. The gap in life expectancy between men in the bottom tenth and top tenth of the income distribution increased from 5 years to 12 years over the same two decades.

Rising longevity inequality has important implications for reforming Social Security. Currently, the program takes in too little money to pay for all benefits promised after 2030. A common proposal to eliminate the funding shortfall is to increase the full retirement age, currently 66. Increasing the age for full benefits by one year has the effect of lowering workers' monthly checks by 6% to 7.5%, depending on the age when a worker first claims a pension.

For affluent workers, any benefit cut will be partially offset by gains in life expectancy. Additional years of life after age 65 increase the number years these workers collect pensions. Workers at the bottom of the wage distribution, however, are not living much longer, so the percentage cut in their lifetime pensions will be about the same as the percentage reduction in their monthly benefit check.

Our results and other researchers' findings suggest that low-income workers have not shared in the improvements in life expectancy that have contributed to Social Security's funding problem.

It therefore seems unfair to preserve Social Security by cutting future benefits across the board. Any reform in the program to keep it affordable should make special provision to protect the benefits of low-wage workers.

Open any magazine aimed at the upper middle class and you’ll find lots of ads about retirement planning: financial firms fighting over which one will ‘advise’ you and get you to invest your money with them.

But, for most people, that isn’t the most important part of retirement planning. In fact, most people don’t have significant retirement savings, so arguing about who or how to invest them is irrelevant. Their “financial planning” is more likely to be about whether and when to pay the credit card bill.

So what kind of retirement planning really matters? There are lots of answers, but here are two of the most important: How long you work and when you apply for Social Security. For most people, these matter far more than whether your savings are invested in stocks or bonds.

Working Longer Requires More than Wishful Thinking. One of the great blessings of modern medicine is that people are living longer. But one of the consequences of that blessing is that unless people work longer and/or save more while they’re working, they’re more likely to run out of money in retirement than ever before. (The decline of traditional pensions, which paid lifetime income benefits, hasn’t helped either.) Most folks know this and are responding. According to a recent survey, 65 percent of baby boomers expect to work past 65.

But those expectations may not be met. Currently, about half of workers stop working before age 65: some are wealthy enough; more often they’re just not healthy enough.

Flexible retirement is more slogan than fact. Moreover, the job market isn’t as flexible as some may hope. Yes, an increasing percentage of seniors are working at least occasionally (~35 percent of men over 60, ~25 percent of women), but that doesn’t mean they’re doing their dream job on their chosen schedule. Increasingly, most of those who do work past 65 work full-time. Twenty years ago about 60 percent of workers over the age of 65 worked part-time; today about 60 percent work full-time.

It’s not clear why part-time work has declined, but one reason may be that employers still haven’t adjusted to the idea. A recent Transamerica Survey found that 66 percent of age 55+ US workers expect they will enter retirement flexibly -- but only 25 percent report that their employer offers the opportunity to move from full-time to part-time. However, the best way for employers to change is for their employees to ask (or have a union that does).

Retirement planning involves more than wishful thinking. If you want a flexible or a phased retirement, you need to know what your options really are – and the time to find out is long before you’re on the verge of retirement.

Defer Applying for Social Security? The other step that matters for most people is when they choose to apply for Social Security. Many apply as soon as they legally can do so, generally at age 62. For most people, that’s a mistake, because it means they will get reduced payments for the rest of their lives. Most others claim their Social Security benefits by the time they reach the “normal retirement age”, which for baby boomers is 66 years. (The normal retirement age is gradually being raised; for those born after 1959 it’s age 67.) For many people, that’s a mistake, too, because your lifetime benefit increases each year that you delay from 62 up to age 70.

How much more will your Social Security be if you start taking it at 70 instead of claiming benefits at the earliest possible age? A lot. For baby boomers, waiting till 70 increases the annual benefit by about 8% or each year of delay. That means instead of taking an annual payment at 62 of $10,000 a year, waiting 8 years means your annual payment will rise to $17,600 – inflation indexed for life. (If you keep working after age 62, then the math can be even more compelling, because Social Security is based on your highest 35 years of earnings.) If you are married, delaying also increases payments to your spouse after you die.

Of course, lots of folks have justifications for taking the lower payment at 62. Some say, “I won’t live long enough to make up the difference” – but in fact most people do live that long and many live longer. Others say, “I need the money to pay my bills.” But if you have savings or home equity, it’s worth using those first and taking Social Security later.

So the next time someone approaches you about moving your 401k money over to them, consider the option they won’t tell you about: spending it first and deferring Social Security. After all, Social Security gives you a guaranteed 8% return for waiting – and an 8% guaranteed return is hard to beat. (But they probably won’t tell you that, either.)

The American people deserve to have a federal government that is both responsive and effective. That simply isn’t the case for more than 1 million people who are awaiting the adjudication of their applications for disability benefits from the Social Security Administration.

Washington can and must do better. This gridlock harms applicants either by depriving them of much-needed support or effectively barring them from work while their cases are resolved because having any significant earnings would immediately render them ineligible. This is unacceptable.

Within the next month, the Government Accountability Office, the nonpartisan congressional watchdog, will launch a study on the issue. More policymakers should follow GAO’s lead. A solution to this problem is long overdue. Here’s how the government can do it.

Congress does not need to look far for an example of how to reduce the SSA backlog. In 2013, the Veterans Administration cut its 600,000-case backlog by 84 percent and reduced waiting times by nearly two-thirds, all within two years. It’s an impressive result.

Why have federal officials dealt aggressively and effectively with that backlog, but not the one at SSA? One obvious answer is that the American people and their representatives recognize a debt to those who served in the armed forces. Allowing veterans to languish while a sluggish bureaucracy dithers is unconscionable. Public and congressional outrage helped light a fire under the bureaucracy. Administrators improved services the old-fashioned way — more staff time. VA employees had to work at least 20 hours overtime per month.

Things are a bit more complicated at SSA, unfortunately. Roughly three quarters of applicants for disability benefits have their cases decided within about nine months and, if denied, decide not to appeal. But those whose applications are denied are legally entitled to ask for a hearing before an administrative law judge — and that is where the real bottleneck begins.

There are too few ALJs to hear the cases. Even in the best of times, maintaining an adequate cadre of ALJs is difficult because normal attrition means that SSA has to hire at least 100 ALJs a year to stay even. When unemployment increases, however, so does the number of applications for disability benefits. After exhausting unemployment benefits, people who believe they are impaired often turn to the disability programs. So, when the Great Recession hit, SSA knew it had to hire many more ALJs. It tried to do so, but SSA cannot act without the help of the Office of Personnel Management, which must provide lists of qualified candidates before agencies can hire them. SSA employs 85 percent of all ALJs and for several years has paid OPM approximately $2 million annually to administer the requisite tests and interviews to establish a register of qualified candidates. Nonetheless, OPM has persistently refused to employ legally trained people to vet ALJ candidates or to update registers. And when SSA sought to ramp up ALJ hiring to cope with the recession challenge, OPM was slow to respond.

In 2009, for example, OPM promised to supply a new register containing names of ALJ candidates. Five years passed before it actually delivered the new list of names. For a time, the number of ALJs deciding cases actually fell. The situation got so bad that the president’s January 2015 budget created a work group headed by the Office of Management and Budget and the Administrative Conference of the United States to try to break the logjam. OPM promised a list for 2015, but insisted it could not change procedures. Not trusting OPM to mend its ways, Congress in October 2015 enacted legislation that explicitly required OPM to administer a new round of tests within the succeeding six months.

These stopgap measures are inadequate to the challenge. Both applicants and taxpayers deserve prompt adjudication of the merits of claims. The million-person backlog and the two-year average waits are bad enough. Many applicants wait far longer. Meanwhile, they are strongly discouraged from working, as anything more than minimal earnings will cause their applications automatically to be denied. Throughout this waiting period, applicants have no means of self-support. Any skills applicants retain atrophy.

The shortage of ALJs is not the only problem. The quality and consistency of adjudication by some ALJs has been called into question. For example, differences in approval rates are so large that differences among applicants cannot plausibly explain them. Some ALJs have processed so many cases that they could not possibly have applied proper standards. In recognition of both problems, SSA has increased oversight and beefed up training. The numbers have improved. But large and troubling variations in workloads and approval rates persist.

For now, political polarization blocks agreement on whether and how to modify eligibility rules and improve incentives to encourage work by those able to work. But there is bipartisan agreement that dragging out the application process benefits no one. While completely eliminating hearing delays is impossible, adequate administrative funding and more, better trained hearing officers would help reduce them. Even if OPM’s past record were better than it is, OPM is now a beleaguered agency, struggling to cope with the fallout from a security breach that jeopardizes the security of the nation and the privacy of millions of current and past federal employees and federal contractors. Mending this breach and establishing new procedures will — and should — be OPM’s top priority.

That’s why, for the sake of everyone concerned, responsibility for screening candidates for administrative law judge positions should be moved, at least temporarily, to another agency, such as the Administrative Conference of the United States. Shortening the period that applicants for disability benefits now spend waiting for a final answer is an achievable goal that can and should be addressed. Our nation’s disabled and its taxpayers deserve better.

Critics of the nation's retirement system regularly complain that the system is in crisis. Too many private companies fail to offer their employees a retirement plan. Many employees who are covered by a plan fail to make contributions to it. Those who do make contributions may contribute too little or invest their savings unwisely. The end result: Many of us will reach retirement age with miniscule pensions or too little savings to enjoy a comfortable old age.

The argument that our retirement system has gaping holes is well founded. The notion that it faces an imminent "crisis" is nonsense. If the system currently faces a crisis, it has faced the same one for the past 40 years. While elderly Americans have seen their incomes and living standards improve in recent decades, the median working-age family has experienced little improvement in its real income. Nonelderly families that depend solely on the earnings of breadwinners who have below-average schooling saw a drop in their incomes.

In recent research with Brookings colleagues, I tracked the real incomes of families headed by aged and nonaged Americans. In the 34 years ending in 2012, the median real income of working-age families climbed a little more than 2 percent (in other words, by less than one-tenth of a percentage point per year). The median real income of families headed by someone past 62 increased a little more than 40 percent. The numbers suggest our retirement system is doing a decent job improving the living standards of the aged. Unfortunately, the labor market is doing a much worse job boosting the living standards of middle-class wage earners.

Critics of the retirement system might worry that it succeeds in protecting the incomes of the middle class elderly but fails to protect the incomes of the poor -- a concern not supported by the evidence. Income inequality has gone up among the elderly as it has among the nonelderly. But older low-income Americans have fared much better than low-income working-age adults. In the late 1950s, by far the highest poverty rate of any age group was that for people over 65. Even in the late 1980s, the elderly had a higher poverty rate than adults between 18-64. Since the middle of the last decade, however, the elderly have had the lowest poverty rate of any age group.

People who warn us of a retirement "crisis" are nonetheless correct in pointing to sizeable holes in the current system. Too few companies, especially small ones, offer their workers a retirement plan. According to recent government estimates, only about half of workers in companies with fewer than 100 employees are offered a retirement plan. Offer rates are higher in bigger companies and in government agencies, but about 30 percent of all employees are not offered any pension or retirement savings plan where they work. When retirement plans are offered, however, workers are very likely to participate in them -- even if they must make a voluntary contribution out of their pretax wages.

What is crucial for a retirement savings plan's success is automatic payroll withholding. Dollars that are withheld from workers' paychecks are harder for workers to spend on something other than retirement savings. A crucial improvement in our current system would be to require all employers to establish automatic payroll withholding for voluntary retirement savings in an IRA (individual retirement account). Companies that already offer a qualified pension or retirement savings plan should be exempt from any extra obligation.

The harshest critics of the current retirement system would go much further than this. Many want to bring back traditional retirement plans that guaranteed workers a specific monthly pension linked to their job tenure, final pay, and age at retirement. The advantages of such a plan for workers are that their employer is typically responsible for funding the plan and for ensuring that pensions are paid, regardless of the ups and downs of financial markets. A big disadvantage is that the promised benefits are not worth much if the worker's career with a company is cut short, either because of a layoff or quitting.

People who are nostalgic for old-fashioned pensions may be right that workers would prefer to be covered by such a plan, despite their disadvantages for short-tenure workers. I'm less persuaded that traditional pensions offer better protection to typical workers than modern 401(k)-type plans. Regardless of the pros and cons of the two kinds of plan, it is wildly unrealistic to think small employers or new employers will want to take on the risks and administrative burdens connected with an old-fashioned pension plan.

All U.S. workers are covered by a traditional, defined-benefit pension: it's called Social Security. It has worked well over the past four decades in protecting and even lifting the incomes of the retired elderly. It may not work as well in the future if benefits are cut substantially to keep the program solvent. Boosting workplace retirement savings is a sensible way to insure future retirees will have adequate incomes, even if Social Security benefits have to be trimmed. An essential first step to boosting savings is to require companies to put a retirement savings plan in every workplace.

Ahead of Tuesday’s primary elections in Ohio, Florida and other states, the 2016 presidential candidates have been talking about the future of Social Security and its funding shortfalls.

Over the next two decades, the money flowing into Social Security will be too little to pay for all promised benefits. The reserve fund will be exhausted soon after 2030, and the only money available to pay for benefits will be from taxes earmarked for the program. Unless Congress and the President change the law before the reserve is depleted, monthly benefits will have to be cut about 21%.

Needless to say, office holders, who must face voters, are unlikely to allow such a cut. Before the Trust Fund is depleted, lawmakers will agree to some combination of revenue increase and future benefit reduction, eliminating the need for a sudden 21% pension cut. The question is: what combination of revenue increases and benefit cuts does each candidate favor?

The candidate offering the most straightforward but least credible answer is Donald Trump. During the GOP presidential debate last week, he pledged to do everything within his power to leave Social Security “the way it is.” He says he can do this by making the nation rich again, by eliminating budget deficits, and by ridding government programs of waste, fraud, and abuse. In other words, he proposed to do nothing specifically to improve Social Security’s finances. Should Trump’s deal-making fail to make us rich again, he offered no back-up plan for funding benefits after 2034.

The other three GOP candidates proposed to repair Social Security by cutting future pensions. No one in the debate, except U.S. Sen. Marco Rubio from Florida, mentioned a specific way to accomplish this. Rubio’s plan is to raise the age for full retirement benefits. For many years, the full retirement age was 65. In a reform passed in 1983, the retirement age was gradually raised to 66 for people nearing retirement today and to 67 for people born after 1960. Rubio proposes to raise the retirement age to 68 for people who are now in their mid-40s and to 70 for workers who are his children’s age (all currently under 18 years old).

In his campaign literature, Rubio also proposes slowing the future rate of increase in monthly pensions for high-income seniors. However, by increasing the full retirement age, Rubio’s plan will cut monthly pensions for any worker who claims benefits at 62 years old. This is the earliest age at which workers can claim a reduced pension. Also, it is by far the most common age at which low-income seniors claim benefits. Recent research suggests that low-income workers have not shared the gains in life expectancy enjoyed by middle- and especially high-income workers, so Rubio’s proposed cut could seriously harm many low-income workers.

Though he didn’t advertise it in the debate, Sen. Ted Cruz favors raising the normal retirement age and trimming the annual cost-of-living adjustment in Social Security. In the long run, the latter reform will disproportionately cut the monthly pensions of the longest-living seniors. Many people, including me, think this is a questionable plan, because the oldest retirees are also the most likely to have used up their non-Social-Security savings. Finally, Cruz favors allowing workers to fund personal-account pensions with part of their Social Security contributions. Although the details of his plan are murky, if it is designed like earlier GOP privatization plans, it will have the effect of depriving Social Security of needed future revenues, making the funding gap even bigger than it is today.

The most revolutionary part of Cruz’s plan is his proposal to eliminate the payroll tax. For many decades, this has been the main source of Social Security revenue. Presumably, Cruz plans to fund pensions out of revenue from his proposed 10% flat tax and 16% value-added tax (VAT). This would represent a revolutionary change because up to now, Social Security has been largely financed out of its own dedicated revenue stream. By eliminating the independent funding stream, Cruz will sever the perceived link between workers’ contributions and the benefits they ultimately receive. Most observers agree with Franklin Roosevelt that the strong link between contributions and benefits is a vital source of the enduring popularity of the program. Social Security is an earned benefit for retirees rather than a welfare check.

Gov. John Kasich does not propose to boost the retirement age, but he does suggest slowing the growth in future pensions by linking workers’ initial pensions to price changes instead of wage changes. He hints he will impose a means test in calculating pensions, reducing the monthly pensions payable to retirees who have high current incomes. Many students of Social Security think this a bad idea, because it can discourage workers from saving for retirement.

All of the Republican candidates, except Trump, think Social Security’s salvation lies in lower benefit payouts. Nobody mentions higher contributions as part of the solution. In contrast, both Democratic candidates propose raising payroll or other taxes on workers who have incomes above the maximum earnings now subject to Social Security contributions. This reform enjoys broad support among voters, most of whom do not expect to pay higher taxes if the income limit on contributions is lifted. Sen. Bernie Sanders would immediately spend some of the extra revenue on benefit increases for current beneficiaries, but his proposed tax hike on high-income contributors would raise enough money to postpone the year of Trust Fund depletion by about 40 years. Hillary Clinton is less specific about the tax increases and benefit improvements she favors. Like Sanders, however, she would vigorously oppose benefit cuts.

None of the candidates has given us a detailed plan to eliminate Social Security’s funding imbalance. At this stage, it’s not obvious such a plan would be helpful, since the legislative debate to overhaul Social Security won’t begin anytime soon. Sanders has provided the most details about his policy intentions, but his actual plan is unlikely to receive much Congressional support without a massive political realignment. Cruz’s proposal, which calls for eliminating the Social Security payroll tax, also seems far outside the range of the politically feasible.

What we have learned from the GOP presidential debates so far is that Republican candidates, with the exception of Trump, favor balancing Social Security through future benefit cuts, possibly targeted on higher income workers, while Democratic candidates want to protect current benefit promises and will do so with tax hikes on high-income workers. There is no overlap in the two parties’ proposals, and this accounts for Washington’s failure to close Social Security’s funding gap.

Editor’s note: The remarks below were delivered to the Committee for a Responsible Federal Budget on release of their report on the SSDI Solutions Initiative. 

I want to thank Marc Goldwein for inviting me to join you for today’s event. We all owe thanks to Jim McCrery and Earl Pomeroy for devoting themselves to the SSDI Solutions Initiative, to the staff of CFRB who backed them up, and most of all to the scholars and practitioners who wrote the many papers that comprise this effort. This is the sort of practical, problem-solving enterprise that this town needs more of. So, to all involved in this effort, ‘hats off’ and ‘please, don’t stop now.’

The challenge of improving how public policy helps people with disabilities seemed urgent last year. Depletion of the Social Security Disability Insurance trust loomed. Fears of exploding DI benefit rolls were widespread and intense.

Congress has now taken steps that delay projected depletion until 2022. Meticulous work by Jeffrey Liebman suggests that Disability Insurance rolls have peaked and will start falling. The Technical Panel appointed by the Social Security Advisory Board, concurred in its 2015 report. With such ‘good’ news, it is all too easy to let attention drift to other seemingly more pressing items.

But trust fund depletion and growing beneficiary rolls are not the most important reasons why policymakers should be focusing on these programs.

The primary reason is that the design and administration of disability programs can be improved with benefit to taxpayers and to people with disabilities alike. And while 2022 seems a long time off, doing the research called for in the SSDI Solutions Initiative will take all of that time and more. So, it is time to get to work, not to relax.

Before going any further, I must make a disclaimer. I was invited to talk here as chair of the Social Security Advisory Board. Everything I am going to say from now on will reflect only my personal views, not those of the other members or staff of the SSAB except where the Board has spoken as a group. The same disclaimer applies to the trustees, officers, and other staff of the Brookings Institution. Blame me, not them.

Let me start with an analogy. We economists like indices. Years ago, the late Arthur Okun came up with an index to measure how much pain the economy was inflicting on people. It was a simple index, just the sum of inflation and the unemployment rate. Okun called it the ‘misery index.’

I suggest a ‘policy misery index’—a measure of the grief that a policy problem causes us. It is the sum of a problem’s importance and difficulty. Never mind that neither ‘importance’ nor ‘difficulty’ is quantifiable. Designing and administering interventions intended to improve the lives of people with disabilities has to be at or near the top of the policy misery index.

Those who have worked on disability know what I mean. Programs for people with disabilities are hugely important and miserably hard to design and administer well. That would be true even if legislators were writing afresh on a blank legislative sheet. That they must cope with a deeply entrenched program about which analysts disagree and on which many people depend makes the problems many times more challenging.

I’m going to run through some of the reasons why designing and administering benefits for people determined to be disabled is so difficult. Some may be obvious, even banal, to the highly informed group here today. And you will doubtless think of reasons I omit.

First, the concept of disability, in the sense of a diminished capacity to work, has no clear meaning, the SSA definition of disability notwithstanding. We can define impairments. Some are so severe that work or, indeed, any other form of self-support seems impossible. But even among those with severe impairments, some people work for pay, and some don’t.

That doesn’t mean that if someone with a given impairment works, everyone with that same impairment could work if they tried hard enough. It means that physical or mental impairments incompletely identify those for whom work is not a reasonable expectation. The possibility of work depends on the availability of jobs, of services to support work effort, and of a host of personal characteristics, including functional capacities, intelligence, and grit.

That is not how the current disability determination process works. It considers the availability of jobs in the national, not the local, economy. It ignores the availability of work supports or accommodations by potential employers.

Whatever eligibility criteria one may establish for benefits, some people who really can’t work, or can’t earn enough to support themselves, will be denied benefits. And some will be awarded benefits who could work.

Good program design helps keep those numbers down. Good administration helps at least as much as, and maybe more than, program design. But there is no way to reduce the number of improper awards and improper denials to zero.

Second, the causes of disability are many and varied. Again, this observation is obvious, almost banal. Genetic inheritance, accidents and injuries, wear and tear from hard physical labor, and normal aging all create different needs for assistance.

These facts mean that people deemed unable to work have different needs. They constitute distinct interest groups, each seeking support, but not necessarily of the same kind. These groups sometimes compete with each other for always-limited resources. And that competition means that the politics of disability benefits are, shall we say, interesting.

Third, the design of programs to help people deemed unable to work is important and difficult. Moral hazard is endemic. Providing needed support and services is an act of compassion and decency. The goal is to provide such support and services while preserving incentives to work and to controlling costs borne by taxpayers.

But preserving work incentives is only part of the challenge. The capacity to work is continuous, not binary. Training and a wide and diverse range of services can help people perform activities of daily living and work.

Because resources are scarce, policy makers and administrators have to sort out who should get those services. Should it be those who are neediest? Those who are most likely to recover full capacities? Triage is inescapable. It is technically difficult. And it is always ethically fraught.

Designing disability benefit programs is hard. But administering them well is just as important and at least as difficult.

These statements may also be obvious to those who here today. But recent legislation and administrative appropriations raise doubts about whether they are obvious to or accepted by some members of Congress.

Let’s start with program design. We can all agree, I think, that incentives matter. If benefits ceased at the first dollar earned, few who come on the rolls would ever try to work.

So, Congress, for many years, has allowed beneficiaries to earn any amount for a brief period and small amounts indefinitely without losing eligibility. Under current law, there is a benefit cliff. If—after a trial work period—beneficiaries earn even $1 more than what is called substantial gainful activity, $1,130 in 2016, their benefit checks stop. They retain eligibility for health coverage for a while even after they leave the rolls. And for an extended period they may regain cash and health benefits without delay if their earnings decline.

Members of Congress have long been interested in whether a more gradual phase-out of benefits as earnings rise might encourage work. Various aspects of the current Disability Insurance program reflect Congress’s desire to encourage work.

The so-called Benefit Offset National Demonstration—or BOND—was designed to test the impact on labor supply by DI beneficiaries of one formula—replacing the “cliff” with a gradual reduction in benefits: $1 of benefit last for each $2 of earnings above the Substantial Gainful Activity level.

Alas, there were problems with that demonstration. It tested only one offset scenario – one starting point and one rate. So, there could be no way of knowing whether a 2-for-1 offset was the best way to encourage work.

And then there was the uncomfortable fact that, at the time of the last evaluation, out of 79,440 study participants only 21 experienced the offset. So there was no way of telling much of anything, other than that few people had worked enough to experience the offset.

Nor was the cause of non-response obvious. It is not clear how many demonstration participants even understood what was on offer.

Unsurprisingly, members of Congress interested in promoting work among DI recipients asked SSA to revisit the issue. The 2015 DI legislation mandates a new demonstration, christened the Promoting Opportunity Demonstration, or POD. POD uses the same 2 for 1 offset rate that BOND did, but the offset starts at an earnings level at or below earnings of $810 a month in 2016—which is well below the earnings at which the BOND phase-out began.

Unfortunately, as Kathleen Romig has pointed out in an excellent paper for the Center on Budget and Policy Priorities, this demonstration is unlikely to yield useful results. Only a very few atypical DI beneficiaries are likely to find it in their interest to participate in the demonstration, fewer even than in the BOND. That is because the POD offset begins at lower earnings than the BOND offset did. In addition, participants in POD sacrifice the right under current law that permits people receiving disability benefits to earn any amount for 9 months of working without losing any benefits.

Furthermore, the 2015 law stipulated that no Disability Insurance beneficiary could be required to participate in the demonstration or, having agreed to participate, forced to remain in the demonstration. Thus, few people are likely to respond to the POD or to remain in it.

There is a small group to whom POD will be very attractive—those few DI recipients who retain a lot of earning capacity. The POD will allow them to retain DI coverage until their earnings are quite high. For example, a person receiving a $2,000 monthly benefit—well above the average, to be sure, but well below the maximum—would remain eligible for some benefits until his or her annual earnings exceeded $57,700. I don’t know about you, but I doubt that Congress would favorably consider permanent law of this sort.

Not only would those participating be a thin and quite unrepresentative sample of DI beneficiaries in general, or even of those with some earning capacity, but selection bias resulting from the opportunity to opt out at any time would destroy the external validity of any statistical results.

Let me be clear. My comments on POD, the demonstration mandated in the 2015 legislation, are not meant to denigrate the need for, or the importance of, research on how to encourage work by DI recipients, especially those for whom financial independence is plausible. On the contrary, as I said at the outset, research is desperately needed on this issue, as well as many others. It is not yet too late to authorize a research design with a better chance of producing useful results.

But it will be too late soon. Fielding demonstrations takes time:

• to solicit bids from contractors,
• for contractors to formulate bids,
• for government boards to select the best one,
• for contractors to enroll participants,
• for contractors to administer the demonstration,
• and for analysts to process the data generated by the demonstrations.

That process will take all the time available between now and 2021 or 2022 when the DI trust fund will again demand attention. It will take a good deal more time than that to address the formidable and intriguing research agenda of SSDI Solutions Initiative.

I should like to conclude with plugs for two initiatives to which the Social Security Advisory Board has been giving some attention.

It takes too long for disability insurance applicants to have their cases decided. Perhaps the whole determination process should be redesigned. One of the CFRB papers proposes just that. But until that happens, it is vital to shorten the unconscionable delays separating initial denials and reconsideration from hearings before administrative law judges to which applicants are legally entitled. Procedural reforms in the hearing process might help. More ALJs surely will.

The 2015 budget act requires the Office of Personnel Management to take steps that will help increase the number of ALJs hired. I believe that the new director, Beth Colbert, is committed to reforms. But it is very hard to change legal interpretations that have hampered hiring for years and the sluggish bureaucratic culture that fostered them.

So, the jury is out on whether OPM can deliver. In a recent op-ed in Politico, Lanhee Chen, a Republican member of the SSAB, and I jointly endorsed urged Congress to be ready, if OPM fails to deliver on more and better lists of ALJ candidates and streamlined procedures for their appointment, to move the ALJ examination authority to another federal organization, such as the Administrative Conference of the United States.

Lastly, there is a facet of income support policy that we on the SSAB all agree merits much more attention than it has received. Just last month, the SSAB released a paper entitled Representative Payees: A Call to Action. More than eight million beneficiaries have been deemed incapable of managing $77 billion in benefits that the Social Security Administration provided them in 2014.

We believe that serious concern is warranted about all aspects of the representative payee program—how this infringement of personal autonomy is found to be necessary, how payees are selected, and how payee performance is monitored.

Management of representative payees is a particular challenge for the Social Security Administration. Its primary job is to pay cash benefits in the right amount to the right person at the right time. SSA does that job at rock-bottom costs and with remarkable accuracy. It is handing rapidly rising workloads with budgets that have barely risen. SSA is neither designed nor staffed to provide social services. Yet determining the need for, selecting, and monitoring representative payees is a social service function.

As the Baby Boom ages, the number of people needing help in administering cash benefits from the Social Security Administration—and from other agencies such as the Veterans Administration—will grow. So will the number needing help in making informed choices under Medicare and Medicaid.

The SSAB is determined to look into this challenge and to make constructive suggestions. We are just beginning and invite others to join in studying what I have called “the most important problem the public has never heard of.”

Living with disabilities today is markedly different from what it was in 1956 when the Disability Insurance program began. Yet, the DI program has changed little. Beneficiaries and taxpayers are pay heavily the failure of public policy to apply what has been learned over the past six decades about health, disability, function, and work.

I hope that SSA and Congress will use well the time until it next must legislate on Disability Insurance. The DI rolls are stabilizing. The economy has grown steadily since the Great Recession. Congress has reinstated demonstration authority. With adequate funding for research and testing, the SSA can rebuild its research capability. Along with the external research community, it can identify what works and help Congress improve the DI program for beneficiaries and taxpayers alike. The SSDI Solutions Initiative is a fine roadmap.

The past few months have seen a flurry of reports on discouraging trends in life expectancy among some of the nation’s struggling populations. Different researchers have emphasized different groups and have tracked longevity trends over different time spans, but all have documented conspicuous differences between trends among more advantaged Americans compared with those in worse circumstances.

In a study published in April, Stanford economist Raj Chetty and his coauthors documented a striking rise in mortality rate differences between rich and poor. From 2001 to 2014, Americans who had incomes in the top 5 percent of the income distribution saw their life expectancy climb about 3 years. During the same 14-year span, people in the bottom 5 percent of the income distribution saw virtually no improvement at all.

Using different sources of information about family income and mortality, my colleagues and I found similar trends in mortality when Americans were ranked by their Social-Security-covered earnings in the middle of their careers. Over the three decades covered by our data, we found sizeable differences between the life expectancy gains enjoyed by high- and low-income Americans. For 50-year old women in the top one-tenth of the income distribution, we found that women born in 1940 could expect to live almost 6.5 years longer than women in the same position in the income distribution who were born in 1920. For 50-year old women in the bottom one-tenth of the income distribution, we found no improvement at all in life expectancy. Longevity trends among low-income men were more encouraging: Men at the bottom saw a small improvement in their life expectancy. Still, the life-expectancy gap between low-income and high-income men increased just as fast as it did between low- and high-income women.

One reason these studies should interest voters and policymakers is that they shed light on the fairness of programs that protect Americans’ living standards in old age. The new studies as well as some earlier ones show that mortality trends have tilted the returns that rich and poor contributors to Social Security can expect to obtain from their payroll tax contributions.

If life expectancy were the same for rich and poor contributors, the lifetime benefits workers could expect to receive from their contributions would depend solely on the formula that determines a worker’s monthly pensions. Social Security’s monthly benefit formula has always been heavily tilted in favor of low-wage contributors. They receive monthly checks that are a high percentage of the monthly wages they earn during their careers. In contrast, workers who earn well above-average wages collect monthly pensions that are a much lower percentage of their average career earnings.

The latest research findings suggest that growing mortality differences between rich and poor are partly or fully offsetting the redistributive tilt in Social Security’s benefit formula. Even though poorer workers still receive monthly pension checks that are a high percentage of their average career earnings, they can expect to receive benefits for a shorter period after they claim pensions compared with workers who earn higher wages. Because the gap between the life spans of rich and poor workers is increasing, affluent workers now enjoy a bigger advantage in the number of months they collect Social Security retirement benefits. This fact alone is enough to justify headlines about the growing life expectancy gap between rich and poor

There is another reason to pay attention to the longevity trends. The past 35 years have provided ample evidence the income gap between America’s rich and poor has widened. To be sure, some of the most widely cited income series overstate the extent of widening and understate the improvement in income received by middle- and low-income families. Nonetheless, the most reliable statistics show that families at the top have enjoyed faster income gains than the gains enjoyed by families in the middle and at the bottom. Income disparities have gone up fastest among working-age people who depend on wages to pay their families’ bills. Retirees have been better protected against the income and wealth losses that have hurt the living standards of less educated workers. The recent finding that life expectancy among low-income Americans has failed to improve is a compelling reason to believe the trend toward wider inequality is having profound impacts on the distribution of well-being in addition to its direct effect on family income.

Over the past century, we have become accustomed to seeing successive generations live longer than the generations that preceded them. This is not true every year, of course, nor is it always clear why the improvements in life expectancy have occurred. Still, it is reasonable to think that long-run improvements in average life spans have been linked to improvements in our income. With more money, we can afford more costly medical care, healthier diets, and better public health. Even Americans at the bottom of the income ladder have participated in these gains, as public health measures and broader access to health insurance permit them to benefit from improvements in knowledge. For the past three decades, however, improvements in average life spans at the bottom of the income distribution have been negligible. This finding suggests it is not just income that has grown starkly more unequal.
