Social Security was designed to provide more generous benefits to lower income earners relative to their pre-retirement earnings than to higher income earners, but that progressivity is declining.
According to a new brief from the Center for Retirement Research at Boston College, the larger increase in life expectancy of recipients with higher incomes and more education compared to those with lower incomes and less education has widened the gap between the amount of Social Security benefits each cohort receives over their lifetimes.
The longer one lives, the more benefits they will collect, which reflects in large part their better health. Higher income earners tend to be healthier than lower income earners although the report notes that it's not clear whether their "improved health outcomes" are due to better medical care, healthier behaviors or stronger health throughout their lives.
A A 2017 National Academy of Sciences study cited by the CRR report found that the present value of Social Security benefits received by men in the highest quintile of income increased from $229,000 for those born in 1930 to $295,000 for those born in 1960 using 2009 dollars, or 29%. In contrast, the benefits received by those in the lowest earnings quintile born in 1960 were lower than the benefits collected by those born in 1930 — $122,000 versus $126,000.
