During the 2016 campaign, a number of presidential candidates have proposed raising the retirement age to 70. Others want to raise the retirement age a bit less, and some don’t favor raising it at all.

When candidates talk about “raising the retirement age,” what they are referring to is the Social Security Full Retirement Age (SSFRA). This is the age at which retirees can begin receiving full Social Security benefits. Starting at age 62, retirees can receive partial benefits.

From 1937 through 2002, the SSFRA was 65. Based on a law from 1983, the SSFRA was gradually raised to 66 by 2009 and will be raised to 67 by 2027. While the age for receiving partial benefits wasn’t lifted, the amount of benefits was reduced. Figure 1 below shows how the SSFRA has and will increase according to current law.

The usual argument for raising the retirement age is the increase in life expectancy since the enactment of Social Security. In 1930, average life expectancy was just 58 for men and 62 for women, compared to a life expectancy at birth of more than 80 today. But most of this increase was due to lower infant mortality, which has little relevance to Social Security’s finances. By comparison, life expectancy for a man at age 65, which does matter for Social Security’s finances, went from 12.7 years in 1940 to 18.4 years by 2006. While this is a substantial increase, it is much smaller than the increase in life expectancy at birth.

Even over the past few decades, there have been real increases in life expectancy for 65-year-olds. Between 1975 and 2006, average life expectancy rose from 14.2 to 18.4 years for 65-year-old men and from 18.7 to 20.9 years for 65-year-old women.

However, since Congress decided to raise the SSFRA in 1983, gains in life expectancy have not been shared evenly across the wage distribution. Between 1987 and 2006, average longevity for 65-year-old men in the bottom half of the wage distribution increased just 9.6 months; for men in the top half of the wage distribution, longevity increased by four years (48 months). (Data are not available for 19831986, so the 1987 figures are the first data points from after the 1983 reforms.) During this same time, the SSFRA rose from 65 years to 65 years and 8 months. Figure 2 shows the number of years that workers could expect to receive full retirement benefits in 1987 and 2006:

As shown in Figure 3 below, this meant that male workers in the bottom half of the wage distribution actually saw essentially no increase in the number of years they could expect to receive full benefits:

But this isn’t the whole story. Unless changes are made to current law, the SSFRA will rise to 67 by the year 2027. Over the 19-year period ending in 2006, life expectancy increased by 0.8 years for 65-year-old men in the bottom half of the wage distribution and by 4.0 years for men in the top half. If life expectancy goes up at the same rate between 2006 and 2027, low-wage workers will see an even greater loss in benefits, while high-wage workers will see an even greater increase:

If the SSFRA were instead raised to 70, low-wage male workers would see their full retirement benefits decline by 3.4 years between 1987 and 2027. While everyone would take a hit, overall the poor would be hurt the most. The top 1 percent of the wealth distribution would see the smallest relative decline in net wealth (Rosnick and Baker 2012 pg. 911).

Those in the top half of the wage distribution have seen a much greater increase in life expectancy than those in the bottom half. However, this doesn’t tell us anything about changes in life expectancy within each half of the wage distribution. For example, we don’t know if people in the bottom fifth of the income or wage distribution have experienced longevity gains equal to people right near the middle. Unfortunately, we don’t have this sort of fine-grained data for 65-year-olds, but we do have a good proxy: the National Academies Press recently published a study looking at changes in life expectancy between 1980 and 2010 for 50-year-olds. It found that while life expectancy had increased substantially for the top 20 percent of income earners, it had fallen for the bottom 20 percent. This is shown in Figure 5 below. (Due to a small sample size, the estimates for women are to be taken with a grain of salt. Having said that, even if the precise findings for women are somewhat off, the general trend of differential increases along the income distribution is clear.)

In a short blog post from 2014, Paul Krugman wrote: “when people call for raising the Social Security and Medicare ages, they’re basically saying that janitors must keep working because corporate lawyers are living longer.” That statement nails the crucial point here: raising the SSFRA to 70 will force poor Americans to keep working for the purpose of financing the Social Security benefits of the rich. So, to paraphrase Krugman: when politicians call for raising the Social Security full retirement age, they’re basically saying that poor workers should receive less Social Security because rich workers are living longer.
