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.

Robert Sargent Shriver, Jr. guided the Peace Corps from its inception in 1961 (when it was a nascent vision of service and citizen diplomacy) to establish a renowned track record of success over the past half century, in which more than 200,000 volunteers and trainees have served in 139 countries.

The legacy of Shriver’s leadership with the Peace Corps and later with the Office on Economic Opportunity and Special Olympics has reached and changed millions of lives—of both those empowered and those who served—from impoverished communities across rural and urban America to huts and villages in developing nations throughout the world. Yet one of the greatest gifts he leaves us is the foundation to build on those accomplishments to scale-up service as a direly needed “soft power” alternative to establish international understanding and collaboration in a volatile world. As Sarge put it, so simply but powerfully: “Caring for others is the practice of peace.”

Sarge Shriver’s unquenchable idealism today is being advanced by a new generation of social entrepreneurs such as Dr. Ed O’Neil, founder of OmniMed and chair of the Brookings International Volunteering Project health service policy group. With the help of Peace Corps volunteers and USAID-supported Volunteers for Prosperity, O’Neil has fielded an impressive service initiative in Ugandan villages that has expanded the capacity and reach of local health-service volunteers engaged in malaria prevention and education on basic hygiene. 

Timothy Shriver, who succeeded his parents, Sarge and Eunice, at the helm of the Special Olympics, speaks eloquently on the move of a second generation from politics to building civil society coalitions promoting soft power acts of service and love, one at a time. This impulse is echoed in the Service World policy platform which hundreds of NGOs and faith-based groups, corporations and universities have launched to scale-up the impact of international service initiatives. This ambitious undertaking was first announced by longtime Shriver protégé former Senator Harris Wofford at a Service Nation forum convened on the morning of President Obama’s Cairo speech in which he called for a new wave of global service and interfaith initiatives.

I had the privilege of serving as a national director of the VISTA program inspired by Shriver and  to work alongside Senator Wofford and John Bridgeland, President George W. Bush’s  former White House Freedom Corps director, who have co-chaired the Brookings International Volunteering Project policy team. Along with Tim Shriver, they have ignited the Service World call to action, together with Michelle Nunn of Points of Light Institute, Steve Rosenthal of the Building Bridges Coalition, Kevin Quigley of the National Peace Corps Association and many others.

The Obama administration and Congress would best honor the life and legacy of Sarge Shriver by calling for congressional hearings and fast- tracking agency actions outlined in the Service World platform and naming the global service legislation after him. Coupled with innovative private-sector and federal agency innovations, the legislation would authorize Global Service Fellowships, link volunteer capacity-building to USAID development programs such as  Volunteers for Prosperity, and double the Peace Corps to reach a combined goal of 100,000 global service volunteers annually—a goal first declared by JFK.

Those who promote opportunity and service as vehicles to advance peace and international collaboration will continue to draw inspiration from Sargent Shriver’s indefatigable quest for social justice―from the time he talked then-Senator John F. Kennedy into intervening in the unjust jailing of Martin Luther King, Jr. to his refusal to accept wanton violence and impoverished conditions in any corner of the world.

An important federal program that tends to fly under the radar received some unprecedented real estate this past weekend--an enormous spread on page A1 of Sunday’s New York Times.

Jason DeParle’s article, and some nifty interactive maps on the Times website, portray the recent rapid growth of the food stamp program, now officially known as the Supplemental Nutrition Assistance Program, or by its rather unfortunate acronym, SNAP. DeParle documents how, in the wake of welfare reform in the mid-1990s, successive administrations--from Clinton to Bush, and now Obama--have worked in a bipartisan fashion to erase the stigma that once haunted the program, and ensure that eligible families receive access to its benefits.

Because welfare reform transformed what was an individual entitlement into a block grant to states, cash welfare caseloads in many states have remained relatively flat despite the worst recession in generations. As a result, food stamps--which remain a federal entitlement--have become an even more important countercyclical tool for fighting poverty, and enrollment has expanded by about one-third since 2007. DeParle charts that rise over the past two years across a broad cross-section of U.S. communities, all of which are feeling the economic pain of rising foreclosures, mounting job losses, and declining family incomes.

Of particular note, the article discusses the significant increases in food stamp receipt occurring in many suburban communities, now that a majority of the nation’s metropolitan poor live outside central cities. Indeed, the counties in which food stamp receipt has doubled, and which have at least 5,000 recipients today, are largely suburbs--around Atlanta, Florida’s Gulf Coast, Austin, and Youngstown. As my colleagues Elizabeth Kneebone and Emily Garr reported earlier this year, however, increases in food stamp enrollment in outer suburban counties have been somewhat lower than might be expected based on the rapid unemployment increases they have suffered. Lack of familiarity, distance to the nearest welfare office, stigma, or real eligibility differences may be to blame for under-enrollment in these farther-out areas.

All of which is to say, as food stamps become the de facto federal support system for millions of families during the next few years of elevated unemployment, plugging participation gaps in suburbia may be an important new frontier for fighting hunger and poverty in America.

Event Information

China’s economy has achieved astonishing growth over the past three decades, but it may be undergoing its most serious test of the reform era. In his newly published book, “China’s Guaranteed Bubble,” Ning Zhu argues that implicit Chinese government guarantees, which have helped drive economic investment and expansion, are also largely responsible for the challenges the country now faces. As growth slows, corporate earnings decline, and lending tightens for small and medium-sized businesses, the leverage ratios of China’s government and its corporations and households all have increased in recent years. How desperate is China’s debt situation, and what can be done to avert a major crisis?

On July 11, the John L. Thornton China Center at Brookings hosted Ning Zhu, deputy dean and professor of finance at the Shanghai Advanced Institute of Finance, Shanghai Jiaotong University. Zhu presented key findings from his research into Chinese sovereign, corporate, and household debt, and also introduced potential remedies to return China to the path of long-term sustainable growth. Following the presentation, Senior Fellow David Dollar moderated a discussion with Zhu before taking questions from the audience.

Nearly a week after the death of 18 year-old Michael Brown in Ferguson, Mo., protests continue in the 21,000-person suburban community on St. Louis’ north side and around the nation.

Amid the social media and news coverage of the community’s response to the police shooting of the unarmed teenager, a picture of Ferguson and its history has emerged.

The New York Times and others have described the deep-seated racial tensions and inequalities that have long plagued the St. Louis region, as well as the dramatic demographic transformation of Ferguson from a largely white suburban enclave (it was 85 percent white as recently as 1980) to a predominantly black community (it was 67 percent black by 2008-2012).

But Ferguson has also been home to dramatic economic changes in recent years. The city’s unemployment rate rose from roughly 7 percent in 2000 to over 13 percent in 2010-12. For those residents who were employed, inflation-adjusted average earnings fell by one-third. The number of households using federal Housing Choice Vouchers climbed from roughly 300 in 2000 to more than 800 by the end of the decade.

Amid these changes, poverty skyrocketed. Between 2000 and 2010-2012, Ferguson’s poor population doubled. By the end of that period, roughly one in four residents lived below the federal poverty line ($23,492 for a family of four in 2012), and 44 percent fell below twice that level.

These changes affected neighborhoods throughout Ferguson. At the start of the 2000s, the five census tracts that fall within Ferguson’s border registered poverty rates ranging between 4 and 16 percent. However, by 2008-2012 almost all of Ferguson’s neighborhoods had poverty rates at or above the 20 percent threshold at which the negative effects of concentrated poverty begin to emerge. (One Ferguson tract had a poverty rate of 13.1 percent in 2008-2012, while the remaining tracts fell between 19.8 and 33.3 percent.)

As dramatic as the growth in economic disadvantage has been in this community, Ferguson is not alone.

Within the nation’s 100 largest metro areas, the number of suburban neighborhoods where more than 20 percent of residents live below the federal poverty line more than doubled between 2000 and 2008-2012. Almost every major metro area saw suburban poverty not only grow during the 2000s but also become more concentrated in high-poverty neighborhoods. By 2008-2012, 38 percent of poor residents in the suburbs lived in neighborhoods with poverty rates of 20 percent or higher. For poor black residents in those communities, the figure was 53 percent.

Like Ferguson, many of these changing suburban communities are home to out-of-step power structures, where the leadership class, including the police force, does not reflect the rapid demographic changes that have reshaped these places.

Suburban areas with growing poverty are also frequently characterized by many small, fragmented municipalities; Ferguson is just one of 91 jurisdictions in St. Louis County. This often translates into inadequate resources and capacity to respond to growing needs and can complicate efforts to connect residents with economic opportunities that offer a path out of poverty.

And as concentrated poverty climbs in communities like Ferguson, they find themselves especially ill-equipped to deal with impacts such as poorer education and health outcomes, and higher crime rates. In an article for Salon, Brittney Cooper writes about the outpouring of anger from the community, “Violence is the effect, not the cause of the concentrated poverty that locks that many poor people up together with no conceivable way out and no productive way to channel their rage at having an existence that is adjacent to the American dream.” 

None of this means that there are 1,000 Fergusons-in-waiting, but it should underscore the fact that there are a growing number of communities across the country facing similar, if quieter, deep challenges every day.

A previous version of this post misstated the Ferguson unemployment rate in 2000. It has since been corrected.

Since passage of the Affordable Care Act in 2010, the last several years have seen a groundswell in physician payment and delivery reforms designed to achieve higher value health care through incentivizing higher quality care and lower overall costs. Accountable care models, for example, are achieving marked progress by realigning provider incentives toward greater risk-sharing and increased payments and shared savings with measured improvements in quality and cost containment. Medical homes are introducing greater care coordination and team-based care management, while the use of episode-based or bundled payments is removing perverse incentives that reward volume and intensity.

These reforms are coming just as the number of highly targeted, highly priced treatments continues to expand. The U.S. Food and Drug Administration (FDA) approved a decade-high 41 novel new drugs in 2014, many of them targeted therapies approved on the basis of increasingly sophisticated progress in genomics and the understanding of disease progression. In areas like oncology, such targeted treatments have grown as a percentage of global oncology market size from 11% in 2003 to 46% in 2013. New brand specialty drug spending in the U.S. is estimated to have been $7.5 billion in 2013, or 69% of total new drug spending. The growing prevalence of these drugs and their cost to the health system are setting the stage for significant flashpoints between industry, payers, and providers, seen most clearly in the debate over hepatitis C treatment costs that roiled stakeholder interactions for most of the past year. 

More of these targeted treatments are in the development pipeline, and a growing number of public policy efforts taking shape in 2015 are focused on accelerating their availability. The House of Representatives' 21st Century Cures Initiative, for example, has released a slew of legislative proposals aimed at promoting breakthrough innovation by increasing the efficiency of drug development and regulatory review. These efforts have significant downstream implications for the pace at which targeted and specialty therapies will become available, their associated costs, and the growing importance of demonstrating value in the postmarket setting.

As payers and providers continue their push toward increased value-based care, more innovative models for connecting such reforms to drug development are needed. Earlier collaboration with industry could enable more efficient identification of unmet need, opportunities to add value through drug development, and clearer input on the value proposition and evidentiary thresholds needed for coverage. Equally important will be unique public-private collaborations that invest in developing a better postmarket data infrastructure that can more effectively identify high value uses of new treatments and support achieving value through new payment reforms.

Stronger collaboration could also improve evidence development and the coverage determination process after a targeted  treatment has gained regulatory approval. Facilitated drug access programs like those proposed by the Medicare Administrative Contractor Palmetto GBA create access points for patients to receive targeted anti-cancer agents off-label while payers and industry gather important additional outcomes data in patient registries. More systematic and efficient use of policies like Medicare's Coverage with Evidence Development (CED), which allows for provisional coverage for promising technologies or treatments while evidence continues to be collected, could enable industry and payers to work together to learn about a medical product's performance in patient populations not typically represented in clinical studies. A CED-type model could be especially useful for certain specialty drugs: data collected as a condition of payment could help payers and providers develop evidence from actual practice to improve treatment algorithms, increase adherence, and improve outcomes. 

Finally, collaborations that support stronger postmarket data collection can also support novel drug payment models that further reward value. Bundled payments that include physician-administered drugs, for example, could encourage providers to increase quality while also incentivizing manufacturers to help promote evidence-based drug use and lower costs for uses that generate low value. Outcomes-based purchasing contracts that tie price paid to a medical product's performance could be another promising approach for high-expense treatment with clearly defined and feasibly measured outcomes.

Many of these ideas are not new, but as manufacturers, payers, providers, and patients move into an increasingly value-focused era of health care, it is clear that they must work together to find new ways to both promote development of promising new treatments while also making good on the promise of value-based health care reforms.

Robert Sargent Shriver, Jr. guided the Peace Corps from its inception in 1961 (when it was a nascent vision of service and citizen diplomacy) to establish a renowned track record of success over the past half century, in which more than 200,000 volunteers and trainees have served in 139 countries.

Voters and policy makers bemoan our crumbling roads, airports, and public transit systems, but few jurisdictions do much about it. The odd thing is that historically low interest rates now make it cheap to fix or improve our public facilities. The mystery is why decision makers have passed on this opportunity.

The sorry state of the nation’s roads, bridges, and public infrastructure has been widely reported. Every few years the American Society of Civil Engineers draws up a report card on U.S. infrastructure, highlighting its strengths and shortcomings in a variety of areas—drinking water systems, wastewater, dams, roads, bridges, inland waterways, ports. The report card spotlights areas where spending on maintenance falls short of the amount needed to keep our infrastructure functioning efficiently. For many kinds of infrastructure, a bigger population and heavier utilization require us to invest in brand new facilities. In its latest report card, the ASCE awards our public infrastructure a grade of D+.

It’s hard to think of a time more attractive for public investment than years when total demand for goods and services is depressed. The Treasury’s borrowing cost for investment funds is near historical lows. Since 2011, the interest rate on 10-year government bonds has averaged 2.3 percent. Savers buying inflation-protected bonds have been willing to lend funds to the federal government at a real interest rate of just 0.22 percent.

So long as there is excess unemployment, especially in the building trades, the labor resources needed to fix or improve public facilities should be abundant and relatively inexpensive. Employment in the construction industry has rebounded as home building and business investment have improved. Nonetheless, construction employment has recovered only half the loss it experienced between its pre-recession peak in 2006 and its post-recession low in 2011. Skilled labor is not nearly as abundant as it was in 2011, but the trend in wage inflation does not suggest employers are bidding up worker salaries.

The federal government’s failure to use fiscal policy and, in particular, public investment policy to bring the nation closer to full employment represents a notable lapse in policymaking, perhaps the most grievous lapse since the crisis began. It unnecessarily prolonged the suffering of the nation’s long-term unemployed and it wasted a rare opportunity to rebuild the nation’s public infrastructure at relatively low cost.

Why did this failure occur? One reason is that policy makers were too optimistic when the financial crisis took place back in 2008. Most public and private forecasts at the time understated the severity of the economic fallout from the bank meltdown. Decision makers in Congress and the Administration may have believed infrastructure investment would be unhelpful in the recovery. Well-conceived infrastructure projects take many months to design and many years to complete. Policy makers may have believed the economic crisis would be over by the time federally infrastructure spending reached its peak.

When forecasters and Democratic policy makers recognized their error, voters had elected a Congress that supported only one kind of fiscal policy to deal with the crisis—big tax cuts focused on high-income tax payers. Whether or not such a policy could have been effective, it would not make additional funds available for infrastructure projects.

Harvard’s Lawrence Summers and Rachel Lipset recently pointed to another reason voters have failed to back a big program to boost infrastructure investment—government ineptitude. In the Boston Globe they documented the painfully slow progress of the Massachusetts Department of Transportation in overhauling a bridge across the Charles River. The bridge, which was built over 11 months back in 1912, has so far required four years for its reconstruction. No end date is in sight. In addition to the over-budget cost of the project, the overhaul has also caused massive and highly visible inconvenience for drivers, cyclists, and pedestrians trying to move between Boston and Cambridge.

Few readers can be under the illusion Boston’s experience is exceptional. Many of us pass near or use public facilities that are being rebuilt or repaired. We often see bafflingly little progress over a span of months or even years. As Summers and Lipset note, the conspicuous failure of public managers to complete capital projects speedily and on budget undermines voters’ confidence that infrastructure projects can be worthwhile.

Despite wide agreement the nation’s infrastructure needs to be modernized, we have made little progress toward that goal. On the contrary, government capital spending has shrunk significantly as a share of the economy. In 2014, net government investment spending on items other than defense dipped to a 60-year low when spending is measured as a percent of GDP. Using this indicator, net government investment has shrunk almost half compared with its level in the first decade of the century. For many reasons this is a good time to fix our public infrastructure. It is also an excellent time to overhaul public management of government capital projects.

Leaders will head to the G-20 Summit in Los Cabos, Mexico, among renewed serious concern about the world economy. The turmoil that started with the U.S. subprime mortgage crisis has resulted in now almost five years of ongoing instability. The emerging market economies fared much better than the advanced economies and pulled out of the crisis already in 2009, but the slowdown we are now facing in 2012 is again global, demonstrating the interdependence in the world economy. The emerging market economies have stronger underlying trend growth rates, but they remain vulnerable to a downturn in the advanced economies. The center of concern is now squarely on Europe, with a recession threatening most European countries, even those that had reasonably good performances so far. After an encouraging start in 2012, the U.S. economy, while not close to a recession, is also showing signs of a slowdown rather than the hoped for steady acceleration of growth. And the slowdown is spreading across the globe.

At a time like this it would be desirable and necessary that the G-20 show real initiative and cohesion. The essays in this collection look at the challenge from various angles. There is concern that the G-20 is losing its sense of purpose, that cohesion is decreasing rather than increasing, and that policy initiatives are reactive to events rather than proactive. Let us hope that at this moment of great difficulty, the G-20 will succeed in giving the world economy a new sense of direction and confidence. It is much needed.
