Event Information

The U.S. government spends billions of dollars each year on computer hardware, software and file servers that may no longer be necessary. Currently, the public sector makes relatively little use of cloud computing, even though studies suggest substantial government savings from a migration to more Internet-based computing with shared resources.

On July 21, the Center for Technology Innovation at Brookings hosted a policy forum on steps to enhance public sector adoption of cloud computing innovations. Brookings Vice President Darrell West moderated a panel of experts, including David McClure of the General Services Administration, Dawn Leaf of the National Institute for Standards and Technology, and Katie Ratte of the Federal Trade Commission. West released a paper detailing the policy changes required to improve the efficiency and effectiveness of federal computing.

Executive Summary

The move to the cloud is one of the defining information technology trends of the early 21st century. By providing businesses, universities, government agencies, and other entities with access to shared and often physically dispersed computing resources, cloud computing can simultaneously offer increased flexibility, reduced cost, and access to a wider array of services.

Cloud computing has also created a set of new challenges. For example, the issues of privacy and security in the cloud are well recognized and have been extensively discussed in the business and popular press. However, one critical issue that has received very little attention with respect to cloud computing is export control.

In the broadest sense, export control relates to regulations that the United States and many other countries have put in place to restrict the export of various sensitive items, information, and software.

There is an inherent tension between cloud computing and export control. While the concept of the cloud is centered on the premise of removing the need to track the details of data movement among various destinations, export control regulations are built largely around restrictions tied to those very movements.

If cloud computing is to reach its full potential, it is critical for providers and users of cloud services to address its implications with respect to export control. It is equally important to adapt the export control regulations to reflect the increasing prevalence of cloud computing in a manner that preserves the ability of American companies to benefit from the efficiencies of the cloud while also ensuring that American national security and foreign policy interests are adequately protected.

Introduction:

In the ebb and flow of Middle East diplomacy, the two interrelated issues of an Israeli-Syrian peace settlement and Washington’s bilateral relationship with Damascus have gone up and down on Washington’s scale of importance. The election of Barack Obama raised expectations that the United States would give the two issues the priority they had not received during the eight years of the George W. Bush administration. Candidate Obama promised to assign a high priority to the resuscitation of the Arab-Israeli peace process, and separately to “engage” with Iran and Syria (as recommended by the Iraq Study Group in 2006).

In May 2009, shortly after assuming office, President Obama sent the assistant secretary of state for Near Eastern affairs, Jeffrey Feltman, and the senior director for the Middle East in the National Security Council, Daniel Shapiro, to Damascus to open a dialogue with Bashar al-Asad’s regime. Several members of Congress also travelled to Syria early in Obama’s first year, including the chairman of the Senate Committee on Foreign Relations, John Kerry, and the chairman of the House Committee on Foreign Affairs, Howard Berman. In addition, when the president appointed George Mitchell as special envoy to the Middle East, Mitchell named as his deputy Fred Hof, a respected expert on Syria and the Israeli-Syrian dispute. Last summer, both Mitchell and Hof visited Damascus and began their give and take with Syria.

And yet, after this apparent auspicious beginning, neither the bilateral relationship between the United States and Syria, nor the effort to revive the Israeli-Syrian negotiation has gained much traction. Damascus must be chagrined by the fact that when the Arab-Israeli peace process is discussed now, it is practically equated with the Israeli-Palestinian track. This paper analyzes the difficulties confronting Washington’s and Jerusalem’s respective Syria policies and offers an approach for dealing with Syria. Many of the recommendations stem from lessons resulting from the past rounds of negotiations, so it is important to understand what occurred.

Last winter, Salafi parties in Egypt proved themselves a formidable political force, winning a quarter of the vote in the country’s first elections in the post-Mubarak era. For many in Washington, the unexpected strength of Egypt’s conservative religious groups raised unsettling questions about the future of U.S.-Egyptian relations and America’s security interests in the region.

Will the political success of Salafis turn Egypt into an anti-American power and strengthen jihadist groups like al-Qa’ida that are bent on using violence against the United States and its allies?

In the Saban Center Middle East Memo, William McCants, a Middle East specialist at CNA and adjunct faculty at Johns Hopkins University, examines the implications of the Salafis’ turn to, and success in, electoral politics. McCants argues that while political participation may not moderate Salafis’ positions on social issues, it will likely erode the strength of their most extreme and violent affiliates. For this reason, America’s interests may be best served when Salafis play a role in post-revolution politics.

• The Lesser of Two Evils: The Salafi Turn to Party Politics in Egypt

The 2016 presidential election confronts the U.S. electorate with political choices more fundamental than any since 1964 and possibly since 1932. That statement may strike some as hyperbolic, but the policy differences between the two major parties and the positions of candidates vying for their presidential nominations support this claim.

A victorious Republican candidate would take office backed by a Republican-controlled Congress, possibly with heightened majorities and with the means to deliver on campaign promises. On the other hand, the coattails of a successful Democratic candidate might bring more Democrats to Congress, but that president would almost certainly have to work with a Republican House and, quite possibly, a still Republican Senate. The political wars would continue, but even a president engaged in continuous political trench warfare has the power to get a lot done.

Candidates always promise more than they can deliver and often deliver different policies from those they have promised. Every recent president has been buffeted by external events unanticipated when he took office. But this year, more than in half a century or more, the two parties offer a choice, not an echo. Here is a partial and selective list of key issues to illustrate what is at stake.

The Affordable Care Act, known as Obamacare or the ACA, passed both houses of Congress with not a single Republican vote. The five years since enactment of the ACA have not dampened Republican opposition.

The persistence and strength of opposition to the ACA is quite unlike post-enactment reactions to the Social Security Act of 1935 or the 1965 amendments that created Medicare. Both earlier programs were hotly debated and controversial. But a majority of both parties voted for the Social Security Act. A majority of House Republicans and a sizeable minority of Senate Republicans supported Medicare. In both cases, opponents not only became reconciled to the new laws but eventually participated in improving and extending them. Republican members of Congress overwhelmingly supported, and a Republican president endorsed, adding Disability Insurance to the Social Security Act.  In 2003, a Republican president proposed and fought for the addition of a drug benefit to Medicare.

The current situation bears no resemblance to those two situations. Five years after enactment of Obamacare, in contrast, every major candidate for the Republican presidential nomination has called for its repeal and replacement. So have the Republican Speaker of the House of Representatives and Majority Leader in the Senate.  

Just what 'repeal and replace' might look like under a GOP president remains unclear as ACA critics have not agreed on an alternative. Some plans would do away with some of the elements of Obamacare and scale back others. Some proposals would repeal the mandate that people carry insurance, the bar on 'medical underwriting' (a once-routine practice under which insurers vary premiums based on expected use of medical care), or the requirement that insurers sell plans to all potential customers. Other proposals would retain tax credits to help make insurance affordable but reduce their size, or would end rules specifying what 'adequate' insurance plans must cover.

Repeal is hard to imagine if a Democrat wins the presidency in 2016. Even if repeal legislation could overcome a Senate filibuster, a Democratic president would likely veto it and an override would be improbable. 

But a compromise with horse-trading, once routine, might once again become possible. A Democratic president might agree to Republican-sponsored changes to the ACA, such as dropping the requirement that employers of 50 or more workers offer insurance to their employees, if Republicans agreed to changes in the ACA that supporters seek, such as the extension of tax credits to families now barred from them because one member has access to very costly employer-sponsored insurance.

In sum, the 2016 election will determine the future of the most far-reaching social insurance legislation in half a century.

Social Security faces a projected long-term gap between what it takes in and what it is scheduled to pay out. Every major Republican candidate has called for cutting benefits below those promised under current law. None has suggested any increase in payroll tax rates. Each Democratic candidate has proposed raising both revenues and benefits. Within those broad outlines, the specific proposals differ.

Most Republican candidates would cut benefits across the board or selectively for high earners. For example, Senator Ted Cruz proposes to link benefits to prices rather than wages, a switch that would reduce Social Security benefits relative to current law by steadily larger amounts: an estimated 29 percent by 2065 and 46 percent by 2090. He would allow younger workers to shift payroll taxes to private accounts. Donald Trump has proposed no cuts in Social Security because, he says, proposing cuts is inconsistent with winning elections and because meeting current statutory commitments is 'honoring a deal.' Trump also favors letting people invest part of their payroll taxes in private securities. He has not explained how he would make up the funding gap that would result if current benefits are honored but revenues to support them are reduced. Senator Marco Rubio has endorsed general benefit cuts, but he has also proposed to increase the minimum benefit. Three Republican candidates have proposed ending payroll taxes for older workers, a step that would add to the projected funding gap.

Democratic candidates, in contrast, would raise benefits, across-the-board or for selected groups—care givers or survivors. They would switch the price index used to adjust benefits for inflation to one that is tailored to consumption of the elderly and that analysts believe would raise benefits more rapidly than the index now in use. All would raise the ceiling on earnings subject to the payroll tax. Two would broaden the payroll tax base.

As these examples indicate, the two parties have quite different visions for Social Security. Major changes, such as those envisioned by some Republican candidates, are not easily realized, however. Before he became president, Ronald Reagan in numerous speeches called for restructuring Social Security. Those statements did not stop him from signing a 1983 law that restored financial balance to the very program against which he had inveighed but with few structural changes. George W. Bush sought to partially privatize Social Security, to no avail. Now, however, Social Security faces a funding gap that must eventually be filled. The discipline of Trust Fund financing means that tax increases, benefit cuts, or some combination of the two are inescapable. Action may be delayed beyond the next presidency, as current projections indicate that the Social Security Trust Fund and current revenues can sustain scheduled benefits until the mid 2030s. But that is not what the candidates propose. Voters face a choice, clear and stark, between a Democratic president who would try to maintain or raise benefits and would increase payroll taxes to pay for it, and a Republican president who would seek to cut benefits, oppose tax increases, and might well try to partially privatize Social Security.

On no other issue is the split between the two parties wider or the stakes in their disagreement higher than on measures to deal with global warming. Leading Republican candidates have denied that global warming is occurring (Trump), scorned evidence supporting the existence of global warming as bogus (Cruz), acknowledged that global warming is occurring but not because of human actions (Rubio, Carson), or admitted that it is occurring but dismissed it as not a pressing issue (Fiorina, Christie). Congressional Republicans oppose current Administration initiatives under the Clean Air Act to curb emission of greenhouse gases.

Democratic candidates uniformly agree that global warming is occurring and that it results from human activities. They support measures to lower those emissions by amounts similar to those embraced in the Paris accords of December 2015 as essential to curb the speed and ultimate extent of global warming.

Climate scientists and economists are nearly unanimous that unabated emissions of greenhouse gases pose serious risks of devastating and destabilizing outcomes—that climbing average temperatures could render some parts of the world uninhabitable, that increases in sea levels that will inundate coastal regions inhabited by tens of millions of people, and that storms, droughts, and other climatic events will be more frequent and more destructive. Immediate actions to curb emission of greenhouse gases can reduce these effects. But no actions can entirely avoid them, and delay is costly.  Environmental economists also agree, with little partisan division, that the way to proceed is to harness market forces to reduce greenhouse gas emissions.” 

The division between the parties on global warming is not new. In 2009, the House of Representatives narrowly passed the American Clean Energy and Security Act. That law would have capped and gradually lowered greenhouse gas emissions. Two hundred eleven Democrats but only 8 Republicans voted for the bill. The Senate took no action, and the proposal died.

Now Republicans are opposing the Obama administration’s Clean Power Plan, a set of regulations under the Clean Air Act to lower emissions by power plants, which account for 40 percent of the carbon dioxide released into the atmosphere. The Clean Power Plan is a stop-gap measure. It applies only to power plants, not to other sources of emissions, and it is not nationally uniform. These shortcomings reflect the legislative authority on which the plan is based, the Clean Air Act. That law was designed to curb the local problem of air pollution, not the global damage from greenhouse gases. Environmental economists of both parties recognize that a tax or a cap on greenhouse gas emissions would be more effective and less costly than the current regulations, but superior alternatives are now politically unreachable.

Based on their statements, any of the current leading Republican candidates would back away from the recently negotiated Paris climate agreement, scuttle the Clean Power Plan, and resist any tax on greenhouse gas emissions. Any of the Democratic candidates would adhere to the Clean Power Plan and support the Paris climate agreement. One Democratic candidate has embraced a carbon tax. None has called for the extension of the Clean Power Plan to other emission sources, but such policies are consistent with their current statements.

The importance of global policy to curb greenhouse gas emissions is difficult to exaggerate. While the United States acting alone cannot entirely solve the problem, resolute action by the world’s largest economy and second largest greenhouse gas emitter is essential, in concert with other nations, to forestall climate catastrophe.

If the next president serves two terms, as six of the last nine presidents have done, four currently sitting justices will be over age 86 and one over age 90 by the time that presidency ends—provided that they have not died or resigned.

The political views of the president have always shaped presidential choices regarding judicial appointments. As all carry life-time tenure, these appointments influence events long after the president has left office. The political importance of these appointments has always been enormous, but it is even greater now than in the past. One reason is that the jurisprudence of sitting Supreme Court justices now lines up more closely than in the past with that of the party of the president who appointed them. Republican presidents appointed all sitting justices identified as conservative; Democratic presidents appointed all sitting justices identified as liberal. The influence of the president’s politics extends to other judicial appointments as well.

A second reason is that recent judicial decisions have re-opened decisions once regarded as settled. The decision in the first case dealing with the Affordable Care Act (ACA), NFIB v. Sibelius is illustrative.

When the ACA was enacted, few observers doubted the power of the federal government to require people to carry health insurance. That power was based on a long line of decisions, dating back to the 1930s, under the Constitutional clause authorizing the federal government to regulate interstate commerce. In the 1930s, the Supreme Court rejected an older doctrine that had barred such regulations. The earlier doctrine dated from 1905 when the Court overturned a New York law that prohibited bakers from working more than 10 hours a day or 60 hours a week. The Court found in the 14^th Amendment, which prohibits any state from ‘depriving any person of life, liberty or property, without due process of law,’ a right to contract previously invisible to jurists which it said the New York law violated. In the early- and mid-1930s, the Court used this doctrine to invalidate some New Deal legislation. Then the Court changed course and authorized a vast range of regulations under the Constitution’s Commerce Clause.  It was on this line of cases that supporters of the ACA relied.

Nor did many observers doubt the power of Congress to require states to broaden Medicaid coverage as a condition for remaining in the Medicaid program and receiving federal matching grants to help them pay for required medical services.

To the surprise of most legal scholars, a 5-4 Supreme Court majority ruled in NFIB v. Sibelius that the Commerce Clause did not authorize the individual health insurance mandate. But it decided, also 5 to 4, that tax penalties could be imposed on those who fail to carry insurance. The tax saved the mandate. But the decision also raised questions about federal powers under the Commerce Clause. The Court also ruled that the Constitution barred the federal government from requiring states to expand Medicaid coverage as a condition for remaining in the program. This decision was odd, in that Congress certainly could constitutionally have achieved the same objective by repealing the old Medicaid program and enacting a new Medicaid program with the same rules as those contained in the ACA that states would have been free to join or not.

NFIB v. Sibelius and other cases the Court has recently heard or soon will hear raise questions about what additional attempts to regulate interstate commerce might be ruled unconstitutional and about what limits the Court might impose on Congress’s power to require states to implement legislated rules as a condition of receiving federal financial aid. The Court has also heard, or soon will hear, a series of cases of fundamental importance regarding campaign financing, same-sex marriage, affirmative action, abortion rights, the death penalty, the delegation of powers to federal regulatory agencies, voting rights, and rules under which people can seek redress in the courts for violation of their rights.

Throughout U.S. history, the American people have granted nine appointed judges the power to decide whether the actions taken by elected legislators are or are not consistent with a constitution written more than two centuries ago. As a practical matter, the Court could not maintain this sway if it deviated too far from public opinion. But the boundaries within which the Court has substantially unfettered discretion are wide, and within those limits the Supreme Court can profoundly limit or redirect the scope of legislative authority. The Supreme Court’s switch in the 1930s from doctrines under which much of the New Deal was found to be unconstitutional to other doctrines under which it was constitutional illustrates the Court’s sensitivity to public opinion and the profound influence of its decisions.

The bottom line is that the next president will likely appoint enough Supreme Court justices and other judges to shape the character of the Supreme Court and of lower courts with ramifications both broad and enduring on important aspects of every person’s life.

***

The next president will preside over critical decisions relating to health care policy, Social Security, and environmental policy, and will shape the character of the Supreme Court for the next generation. Profound differences distinguish the two major parties on these and many other issues. A recent survey of members of the House of Representatives found that on a scale of ‘liberal to conservative’ the most conservative Democrat was more liberal than the least conservative Republican. Whatever their source, these divisions are real.  The examples cited here are sufficient to show that the 2016 election richly merits the overworked term 'watershed'—it will be the most consequential presidential election in a very long time.

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.

Gary Burtless, a senior fellow in Economic Studies, explains new research on the growing longevity gap between high-income and low-income Americans, especially among the aged.

“Life expectancy difference of low income workers, middle income workers, and high income workers has been increasing over time,” Burtless says. “For people born in 1920 their life expectancy was not as long typically as the life expectancy of people who were born in 1940. But those gains between those two birth years were very unequally distributed if we compare people with low mid-career earnings and people with high mid-career earnings.” Burtless also discusses retirement trends among the educated and non-educated, income inequality among different age groups, and how these trends affect early or late retirement rates.

Also stay tuned for our regular economic update with David Wessel, who also looks at the new research and offers his thoughts on what it means for Social Security.

Later retirement, inequality and old age, and the growing gap in longevity between rich and poor

Disparity in Life Spans of the Rich and the Poor Is Growing

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.

Editor's note: This piece originally appeared in The Los Angeles Times. 

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.
