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.

Editor’s note: This week the Democrats gather in Philadelphia to nominate a candidate for president and adopt a party platform. Given that there are no minority reports to the Democratic platform, it is likely that it will be adopted as-is this week. And so we can begin the comparison of the two major party platforms. For those who say there are no differences between the Republican and Democratic parties, just read the platforms side-by-side. In many instances, the differences are—as Donald Trump would say, yuuuge. But in one surprising instance, the two parties actually agree. This piece walks readers through one of the biggest contrasts, while an earlier piece by Elaine Kamarck detailed a striking similarity.

When it comes to Republicans and the environment, black is the new green. In addition to denouncing “radical environmentalists” and calling for dismantling the EPA, the platform adopted in Cleveland yesterday calls coal “abundant, clean, affordable, reliable domestic energy resource” and unequivocally opposes “any” carbon tax.

Meanwhile, Democrats are moving in the opposite direction. By the time the party’s draft 2016 platform emerged from the final regional committee meeting in Orlando, it contained a robust section on environmental issues in general and climate change in particular. One of the many amendments adopted in Orlando contains the following sentence: “Democrats believe that carbon dioxide, methane, and other greenhouse gases should be priced to reflect their negative externalities, and to accelerate the transition to a clean energy economy and help meet our climate goals.” In plain English, there should be what amounts to a tax (whatever it may be called) on the atmospheric emissions principally responsible for climate change, including but not limited to CO2.

As Brookings’ Adele Morris pointed out in a recent paper, this proposal raises a host of design issues, including determining initial price levels, payers, recipients, and uses of revenues raised. It would have to be squared with existing federal tax, climate, and energy policies as well as with climate initiatives at the state level.

But these devilish details should not obstruct the broader view: To the best of my knowledge, this is the first time that the platform of a major American political party has advocated taxing greenhouse gas emissions. Many economists, including some with a conservative orientation, will applaud this proposal. Many supporters and producers of fossils fuels will be dismayed.

It remains to be seen how the American people will respond. In a survey conducted in 2015 by Resources for the Future in partnership with Stanford University and the New York Times, 67 percent of the respondents endorsed requiring companies “to pay a tax to the government for every ton of greenhouse gases [they] put out,” with the proviso that all the revenue would be devoted to reducing the amount of income taxes that individuals pay. Previous surveys found similar sentiments: public support increases sharply when the greenhouse gas tax is explicitly revenue-neutral and declines sharply if it threatens an overall increase in individual taxes.

Once this plank of the Democratic platform becomes widely known, Republicans are likely to attack it as yet another example of Democrats’ propensity to raise taxes. The platform’s silence on the question of revenue-neutrality may add some credibility to this charge. Much will depend on the ability of the Democratic Party and its presidential nominee to clarify its proposal and to link it to goals the public endorses.

Hillary Clinton isn’t often in the business of offering unsolicited advice to her Republican—or even Democratic—rivals in the presidential race. However, in a CNN interview with Alisyn Camerota on January 12, 2015, Hillary Clinton did just that. She did something quite taboo. She talked about the presidential transition.

Her comments did not flow from confidence that she would be elected president—a confidence she may indeed have. Her words came from experience, pragmatism and reality. They were words that did not simply reflect her own approach to a candidacy or a prospective administration. It was advice to everyone running for president about the right thing to do—not for themselves, but for the American public.

Clinton said:

I want to think hard—if I do get the nomination, right then and there—how we organize the White House, how we organize the Cabinet, what’s the legislative agenda. You know, the time between an election and an inauguration is short. You can’t wait. I mean, you can’t take anything for granted; you need to keep working as hard as you possibly can. But I think it’s important to start planning because we know what happens if you get behind in getting your agenda out, in getting your appointments made. You lose time, and you’re not doing the work the American people elected you to do.

Presidential candidates almost never speak of a transition until they are declared the president-elect in the late hours of the Tuesday following the first Monday in November. Candidates fear being accused of taking the election for granted, or “measuring the drapes.” They worry such planning will signal to voters an off-putting overconfidence.

Those fears may be legitimate, but acting on those concerns can be dangerous. If a voter believes a candidate should not prepare for a new administration until they are officially elected, that leaves the president-elect about 11 weeks to ready themselves for the busiest, most complicated, most important job in the world. In those 11 weeks, a president-elect would need to think not just about the 15 Cabinet secretaries who serve as the most visible political appointees in government, but literally hundreds and thousands of other posts. (One dirty little secret is that the President of the United States appoints over 3,000 people to his or her administration.)

Presidents have to think about the structure, order, and sequence of their legislative agenda. They need to communicate their intentions and plans to congressional leadership. They need to think about organizing a White House. The truth is from president to president, the White House looks the same from the outside, but is structured and functions dramatically differently on the inside. Presidents have myriad important decisions to make that will set the tone and agenda for the following four years and will affect every American in some way. Eleven weeks is not enough time. Clinton acknowledges this.

Clinton’s “bold” statement actually reflects a reality in American politics. As soon as an individual accepts his or her party’s presidential nomination, they are entitled to funding, office space, and government email and technology as part of the transition process. The Office of Personnel Management is involved, as is (of late) the Office of Presidential Personnel for the outgoing administration. The presidential transition is an essential part of democracy, policymaking, administration, and the continuity of government. Every four years, the government supports two transitions—one that comes to be and one that closes up shop.

In one way however, Hillary Clinton is entirely wrong. Waiting until you receive the nomination is too late to begin thinking about the transition. As I have written before, every presidential candidate should start thinking about a transition as soon as they announce their candidacy. They don’t need a full Cabinet chosen on Day 1 of the campaign, but they should designate one or two close advisers to organize for the process, begin considering names for posts, think through the types of policies to propose in the first 100 days, and begin what is one of the most complicated managerial tasks in the world.

Hillary Clinton is right “it is important to start planning,” and it’s also never too early to do so. I hope Clinton’s claim that one should start upon securing the nomination is a reflection of that fear of the “drape measuring” accusation. I hope she is planning her transition now. I hope Bernie Sanders and Ted Cruz and Donald Trump and John Kasich and everyone else is planning their transition right now. It’s essential. Clinton knows the challenges of setting up a White House and the complications that early disorganization can cause; she saw that dysfunction first hand in 1993. But most candidates have also worked in or around the White House or have been in politics long enough to know the importance of an effective transition. And candidates who haven’t, like Donald Trump and Carly Fiorina, should be more inclined to set up a transition early, as they have more managerial experience than anyone else in the race.

To this end, I have a modest proposal. It probably won’t happen. It’s likely one that candidates would fear, and it would likely only be effective if everyone is on board. Every current presidential candidate should sign a pledge committing to two things. First, by February 1, 2016, they will designate at least one staffer, adviser or confidante as a transition director.  Second, they will not publicly criticize another candidate—of either party—for having a transition staffer or team in place. Call it a “Transition Truce.” But the reality is that such a pledge—and the actions behind it—are essential for a better functioning, better prepared, more effective administration, no matter who it is who swears the oath exactly one year from today.

There is a marriage gap in America. This is not just a gap in choices and actions, but in norms and attitudes. Each generation is more liberal, on average, when it comes to issues like premarital relationships, same-sex marriage, and divorce. But generational averages can obscure other divides, including ideology—which in many cases is a more powerful factor.

Take opinions on the most important prerequisites for marriage, as explored in the American Family Survey conducted earlier this year by Deseret News and the Center for the Study of Elections and Democracy (disclosure: I am an adviser to the pollsters). There is widespread agreement that it is best to have a stable job and to have completed college before tying the knot. But there is less agreement in the 3,000-person survey on other questions, including premarital cohabitation.

In response to the question of whether it is “important to live with your future spouse before getting married,” a clear gap emerges between those who identify as Democrats and those who identify as Republicans. This gap trumps the generational one, with younger Republicans (under 40) more conservative than Democrats over the age of 40:

The importance of family stability for a child’s wellbeing and prospects is well-documented, not least in Isabel Sawhill’s book, Generation Unbound. The question is not whether stability matters, but how best to promote it. To the extent that biological parents stay together and provide a stable environment, it doesn’t much matter if they are married. For children living with both biological parents, there is no difference in outcomes between those being raised by a married couple compared to a cohabiting couple, according to research by Wendy Manning at Bowling Green State University.

But people who marry are much more likely to stay together:

Marriage, at least in America, does seem to act as an important commitment device, a “co-parenting” contract for the modern world, as I’ve argued in an essay for The Atlantic, “How to Save Marriage in America.”

Cohabitation can signal radically different situations. A couple who plan to live together for a couple of years, then marry, and then plan the timing of having children are very different from a couple who start living together, accidentally get pregnant, and then, perhaps somewhat reluctantly, get married.

There is some evidence that cohabitation is in fact becoming a more common bridge to marriage and commitment. First-time premarital cohabiting relationships are also lasting longer on average and increasingly turn into marriage: around seven in ten cohabiting couples are still together after three years, of whom four have married.

In the end what matters is planning, stability, and commitment. If cohabitation is a planned prelude to what some scholars have labeled “decisive marriages,” it seems likely to prove a helpful shift in social norms, by allowing couples to test life under the same roof before making a longer-term commitment. Sawhill’s distinction between “drifters” and “planners” in terms of pregnancy may also be useful when it comes to thinking about cohabitation, too.
