A study by the Center for Retirement Research at Boston College found that the delayed credit is still about right, with the exception of the highest earners, who tend to outlive actuarial averages and reap the highest extra benefit. Conversely, the group hurt the most are low-income filers, who tend to claim earlier and effectively are overcharged for doing so. Moreover, the increase in FRA from 65 to 67, enacted in the reforms of 1983, effectively increased the penalty for earlier files. Claimers with an FRA of 67 will receive five years of early filing reductions rather than three.

It’s Time to Revisit Social Security’s Early and Delayed Claiming Formulas — https://www.morningstar.com/articles/1029357/its-time-to-revisit-social-securitys-early-and-delayed-claiming-formulas

The first sentence from the above paragraph caught my eye. So I went on to the BC website.

People can claim Social Security from 62 to 70, with adjustments to keep lifetime benefits the same, on average, regardless of claiming age. The question is whether the adjustments, set decades ago, are still correct, given the decline in interest rates and increase in life expectancy. For the average worker, the analysis shows that the reduction for claiming early is currently too large while the increase for claiming late is about right.

Higher earners – who live longer and claim later – get a really good deal under the current system.

Are Social Security’s Actuarial Adjustments Still Correct? — https://crr.bc.edu/briefs/are-social-securitys-actuarial-adjustments-still-correct/

People with more money tend to live longer. People who defer claiming social security benefits until beyond FRA (full retirement age) are generally healthier, expect to live longer, and are financially secure enough to delay claiming. If the SSA decides to enhance benefits for early retirees it would be a good thing for a lot of people, especially those who have been severely impacted by the pandemic.
