In last Thursday’s GOP debate, Marco Rubio, Ted Cruz, Jeb Bush and Chris Christie managed to avoid mentioning their common proposal to “reform entitlements” by raising the Social Security retirement age from 67 to 70. That was probably a good idea. Their proposal only demonstrates their lack of understanding about the demographics of older Americans, especially the dramatic disparities in their life expectancy associated with education and race. Recent research on life expectancy indicates that their proposed change would effectively nullify Social Security for millions of Americans and sharply limit benefits for many millions more.. While many people in their 30s and 40s today can look forward to living into their 80s, the average life expectancy for the majority of Americans who do not hold a college degree hovers closer to 70, or the average life expectancy for all Americans in 1950.

The Widening Inequalities in the Life Spans of Americans

This research, summarized recently in a study published in Health Affairs, found that life expectancy for various age cohorts of Americans is closely associated with both educational achievement and race. For example, the average life expectancy for college-educated American men who were age 25 in 2008, or age 33 today, is 81.7 years for whites and 78.2 years for blacks. (Table 1, below) By contrast, the projected, average life span of high-school educated males, also age 25 in 2008 or 33 today, is 73.2 years for whites and 69.3 years for blacks. Women on average live longer than men; but similar disparities based on education and race are evident. The average life expectancy of women age 25 in 2008, or 33 years old today, was 79 years for whites and 75.4 years for blacks for those with a high school diploma, and 84.7 years for whites and 81.6 years for blacks with college degrees. Most disturbing, the average life expectancy of Americans age 25 in 2008 without a high school diploma is just 68.6 years for white men, 68.2 years for black men, 74.2 years for white women, and 74.9 years for black women. Surprisingly, the researchers found that Hispanics in this age group have the longest life expectancies, even though they also have the lowest average levels of education. Since these data are anomalous and may reflect sampling problems, we will focus mainly on the life-expectancy gaps between African American and white Americans.

Tallying How Many People Are Adversely Affected

Census data on the distribution by education of people age 25 to 34 in 2010 (ages 30 to 39 in 2015) provide a good estimate of how many Americans are adversely affected by these growing differences. Overall, 56.3 percent of all Americans currently in their 30s fall are high school graduates or left school without a high school diploma, educational groups with much lower average life expectancies. (Table 2, below) More precisely, 10.1 percent or almost 4.8 million Americans in their 30s today lack a high school diploma, and 46.2 percent or 18.9 million thirty-somethings have high school diplomas and no further degrees. All told, they account for 23,702,000 Americans in their 30s; and among older Americans, the numbers and percentages are even higher.

Since race as well as education are major factors associated with differences in life expectancy, we turn next to education by race (Table 3, below). The totals differ modestly from Table 2, because Census data on education by race cover ages 30-39 in 2014, while Table 2 covers age 30-39 in 2015 (ages 25-34 in 2010).

• Among people in their 30s today, 45.4 percent of whites or 10,613,000 Americans have a high school degree or less – and their average life expectancy is 9.4 years less than whites in their 30s with a college or associate degree.
• Among people in their 30s todays, 64.4 percent of blacks or 3,436,000 Americans have a high school degree or less – and their life expectancy is 8.6 years less than blacks in their 30s with an B.A. or associate degree, and 11.6 years less than whites with a college or associate degree..
• Among people in their 30s today, 75.6 percent of Hispanics or 6,243,000 Americans have a high school degree or less – and their life expectancy is 5.0 years less than Hispanics in their 30s with a college or associate degree.

As a policy matter, these data tell us that across all communities—white, black, Hispanic—improvements in secondary education to prepare everyone for higher education, and lower-cost access to higher education, can add years to the lives of millions of Americans.

Preserving Meaningful Access to Social Security Benefits

The widening inequalities in average life expectancy associated with race and education have more direct policy implications for Social Security, because the number of years that people can claim its benefits depends on their life spans. The growing inequalities in life expectancy translate directly into growing disparities in the years people can claim Social Security benefits, based on their education and race. Assuming that Americans in their 30s today retire at age 67 (the age for full benefits for this age group), they can expect to claim retirement benefits, on average, ranging from 1.2 years to 19.3 years, based on their education and race. (Table 4, below)

The most pressing issues of life expectancy and Social Security involve white males, black males, and black females without college degrees: Among Americans age 33 today, white and black men without high school diplomas and black males with high school degrees, on average, can expect to live long enough to collect benefits for less than three years. Similarly, white and black women without high school diplomas and black women with high school degrees, on average, can expect to collect benefits for less than eight years. Together, they account for 25.2 percent of whites and 64.4 percent of blacks in their 30s today. By contrast, male and female white college graduates age 33 today, on average, can expect to collect Social Security for between 14.7 and 17.7 years, respectively; and 33-year old black men and women with college degrees, on average, will claim benefits for 11.2 to 14.6 years, respectively.

These findings dictate that proposals to raise the Social Security retirement age should be rejected as a matter of basic fairness. Among this year’s presidential hopefuls, as noted earlier, Ted Cruz, Marco Rubio, Jeb Bush and Chris Christie all have called for raising the retirement age to 70 years. Under this policy, black men in their 30s today without a college degree and white men now in their 30s without a high school diploma, on average, would not live long enough to collect any Social Security. The change would reduce the average number of years of Social Security for Americans in their 30s today,

• From 1.6 years to -1.4 years for white men with no high school diploma,
• From 1.2 years to -1.8 years for black men with no high school diploma, and
• From 2.3 years to – 0.7 years for black, male high-school graduates.

Furthermore, among Americans in their 30s today, white and black women without a high school diploma, white male high school graduates, and black female high school graduates, would live long enough, on average, to collect Social Security for just 3.2 to 5.4 years. The GOP change reduce the average number of years of Social Security for Americans in their 30s today,

• From 6.2 years to 3.2 years for white, male high school graduates,
• From 7.2 years to 4.2 years for white women with no high school diploma,
• From 7.9 years to 4.9 years for black women with no high school diploma, and
• From 8.4 years to 5.4 years for black, female high-school graduates.

All told, proposals to raise the retirement age to 70 years old would mean, based on the average life expectancy of Americans in their 30s today, that 25.2 percent of whites in their 30s and 64.4 percent of blacks of comparable age, after working for 35 years or more, would receive Social Security benefits for 5.4 years or less.

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.’

Editor's note: This piece originally appeared in Fortune.

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.

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.

Editor's note: This piece originally appeared in Politico.

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: This piece originally appeared in Fortune.

The long-term finances of Social Security are in bad shape. Its reserves are expected to run out in less than 20 years, and under current law that will force cuts in benefits.

Some experts argue that the best way to get the system’s finances back in shape would be to raise the full retirement age above the scheduled 67. That would bolster the program’s finances in two ways. First, by increasing payroll tax revenues, because people would work longer. And second, by reducing the period each American would collect benefits.

That approach might seem fair, since on average Americans are living longer. Life expectancy is more than 15 years higher than when Social Security began in 1937.

But we are not all average. Lower-income Americans have not seen much increase in life expectancy, while more affluent people have. Thus raising the retirement age would cut total lifetime benefits proportionately more for those on the bottom rungs of the income ladder.

But let’s think differently about Social Security. Right now, monthly checks are linked to a person’s earnings during their working years. So, better-paid workers get bigger checks. True, lower-paid workers pay much less in Social Security payroll taxes and usually get back much more than they paid in taxes – even counting in interest on their tax contributions. Upper-income workers typically get back a lot less than they paid in, despite larger checks.

But low-wage workers still get smaller Social Security checks to try to meet their monthly needs in retirement. Many end up falling below the poverty line and have to apply for means-tested assistance from Supplementary Security Income (SSI), another part of the Social Security system.

What if we were to recast regular Social Security as true insurance? Insurance is something that pays out only when things go wrong. If you don’t have a car crash, or your house doesn’t burn down, you don’t get your premiums back later in life. What you do get is protection and peace of mind.

So imagine Social Security as insurance protection against being financially insecure in retirement. If it were that, it would be very different from today.

For one thing, we would want the lowest-income retirees to get the largest regular check – assuming they had dutifully paid their payroll tax “premiums” when working – and also enough to keep them comfortably out of poverty without having to rely on SSI. Some retirees with a modest income from, say, an IRA, might still need a small Social Security “insurance payout” to maintain a reasonable standard of living.

In a true insurance model like this, retired Americans with healthy income from assets would get no Social Security check at all, rather than getting the largest checks as they do today. If Social Security is seen as insurance against financial insecurity then Warren Buffet clearly doesn’t need a check. Nor do other older Americans for whom a monthly Social Security check is just a little bit more icing on an already rich cake.

If we reformed Social Security to make it more like real insurance, we’d need to do it gradually so people could plan, with the changes only fully affecting workers who are perhaps in their early 40s today. There would be a significantly higher basic benefit check for the least well-off. For retired singles with retiree income over, say, $25,000 in today’s dollars, the check would be reduced according to income until for a retiree with, say, $100,000 in other income there would be no check at all.

With this reform, regular Social Security would more efficiently protect the elderly against economic insecurity and from poverty without the stigma of applying for SSI “welfare.” And it would help put the program on a more secure footing. To be sure, some would say it’s not fair that many Americans would pay Social Security taxes and get nothing in return. But that misses the point that Social Security should be insurance. And what’s really not fair is that many today pay high payroll taxes for a check that doesn’t keep them out of poverty.

Some other critics might argue that without checks for all, the coalition needed to preserve Social Security would unravel. I doubt that very much. Social Security has an iconic status in America and there is no public support for ending it.

So let’s not allow Social Security’s deteriorating finances to make it a steadily worse deal for those who need it most. It’s time instead to look at a reform that refocuses its mission on insuring financial security for seniors.

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.

Rumor has it that an economist started hitting the gym after finishing two milestone research papers, in expectation of a Nobel Prize, which is only rewarded to a living person. Almost no one denies that greater expectations translate into healthier behaviors, while the converse rarely enters the health policy discussion: expectations of a less-than-desirable future may lead to unhealthy behaviors, including smoking, excessive drinking, sedentary lifestyles, and drug abuse. The health issues of the deprived may have a deeper root in economics.

Professor Zhu Xi from Shanghai Jiao Tong University and I found evidence of this in our working paper “Affordable Care Encourages Healthy Living: Theory and Evidence from China's New Cooperative Medical Scheme”. Standard economic theory predicts that providing medical insurance encourages unhealthy behavior by mitigating economic consequences. We developed a novel theoretical framework in which the opposite is possible because insurance makes longevity more affordable and thus desirable.

We test the theory utilizing a unique experiment of China introducing the New Cooperative Medical Scheme, unique in its long-term credibility necessary for their proposed channel. This scheme reduces cigarette use by around 9% and bolsters subjective perception of the importance of physical exercise and healthy diet. These effects depend significantly on the number of children and the local culture of elderly care. We can rule out alternative explanations of these robust results. The empirical evidence affirms a causal link between concerns about negative bequest and unhealthy behavior, and how to break it.

Breaking the causal link would not be an easy task, because bringing a brighter future to the deprived would not be. But this does not revoke the necessity of considering this “expectation” mechanism in designing health policies. For example, it is trendy to study how smokers may substitute other tobacco products for cigarettes and the ensuing health consequences. According to our analytical framework, the substitution could be broader, that is, a person expecting a miserable future would consciously or unconsciously resort to other means of shortening life. Case and Deaton, in their sensational paper, pinned down drug and alcohol poisonings, suicide, and chronic liver diseases and cirrhosis as the causes of the rising mortality in midlife among white Americans. The war against tobacco use may be complicated by this potential substitution.

In general, recognizing the source of a problem is the first step in solving it. The association between income and life expectancy in the United States is well identified by a Brookings study by Bosworth and Burke and a paper by Chetty et al. The hypothesis that poverty may rationally trigger unhealthy behaviors and thus shorter life expectancy is under-explored.

Our research suggests that constructing a social safety net – by subsidizing health or old-age insurance, for example – brightens the future and thus promotes healthy living. Libertarians who believe in “from each as they choose, to each as they are chosen” may frown upon the idea of expanding the government for the sake of saving people from their own poor choices. As usual, an argument could be made that the positive externality outweighs the cost. In this case, a better social safety net can make a person more forward-looking and thus more beneficial to the society.

Discovering hidden incentives and mechanisms is one of the primal tasks of economists. Our research suggests, surprisingly, that both the Center of Disease Control and Prevention and the Department of the Treasury are important players in promoting healthy living. Let them be.

No. We should exempt workers earning the lowest wages.

Social Security faces a serious funding problem. The program takes in too little money to pay all that has been promised to future beneficiaries. Government forecasters predict Social Security’s reserve fund will be depleted between 2030 and 2034. There are two basic ways we can eliminate the funding gap: cut benefits or increase contributions. A common proposal is to increase the age at which workers can claim full retirement benefits. For people nearing retirement today, the full retirement age is 66. As a result of a 1983 law, that age will rise to 67 for workers born after 1959.

When policymakers urge us to raise the retirement age, they are proposing to increase the full retirement age beyond 67, possibly to 70, for workers now in their 30s or 40s. This saves money, but it also cuts monthly retirement benefits by the same percentage for every worker, unless workers delay claiming benefits. The policy might seem fair if workers in future generations could all expect to share in gains in life expectancy. However, new research shows that gains in life expectancy have been very unequal, with the biggest improvements among workers who earn top incomes. Life expectancy gains for workers with the lowest incomes have been small or negligible.

If the full retirement age were raised, future retirees with high lifetime earnings can expect to receive some compensation when their monthly benefits are cut. Because they can expect to live longer than today’s retirees, they will receive benefits for a longer span of years after 65. For low-wage workers, there is no compensation. Since they are not living longer, their lifetime benefits will fall by the same proportion as their monthly benefits. Thus, “raising the retirement age” is a policy that cuts the lifetime benefits of future low-wage workers by a bigger percentage than it does of future high-wage workers.

The fact that low-wage workers have seen small or negligible gains in life expectancy signals that their health when they are past 60 is no better than that of low-wage workers born 20 or 30 years ago. This suggests their capacity to work past 60 is no better than it was for past generations. A sensible policy for cutting future benefits should therefore preserve current benefit levels for workers who have contributed to Social Security for many years but have earned low wages.
