Raise Social Security Taxes — and Cut Benefits, Too

There are two processes that we cannot escape: aging and math. This applies not only to human beings but also to large government social-insurance programs.

Last week the Social Security Administration released its annual trustees report, and the news was not good. Starting in the fourth quarter of 2032, one quarter earlier than previously projected, Social Security is set to pay only 78% of benefits. Such a broad cut is unlikely — Social Security is too popular, and the elderly rely on it too much. Even missing a cost-of-living increase is unthinkable. So something else has to happen.

The news is worse than expected because a lower fertility rate, less immigration, and provisions from last year’s budget and tax law are combining to decrease expected tax revenues. More generally, however, these negative shocks shouldn’t be a surprise, since at least two of those factors are deliberate policies.

The hard truth is that getting Social Security back on track will require both benefit cuts and tax increases. That means almost everyone will have to pay more and get less, including virtually everyone reading this (and writing it, for that matter).

We will not grow our way out of it. Even if AI increases GDP, wages will likely increase with productivity — and while that will increase tax revenues, it will also increase liabilities. Part of the reason Social Security is becoming unsustainable is not only that society is aging, but also that benefits have become more generous. They are initially calculated by taking average lifetime earnings and indexing them to wage growth, instead of price inflation. Then once the benefit is calculated, it rises with price inflation. The idea is to ensure stable living standards.

But because wages generally grow faster than inflation, Social Security has become more generous over time. The figure below is the monthly benefit going to high earners, adjusted for inflation, based on year of retirement.



Despite these well-known financial challenges, which cause retirees so much uncertainty, it has become popular for politicians to say they won’t touch anyone’s benefits. This amounts to ignoring the problem. If they say anything, they tend to revert to their favorite promise: Someone else — generally the wealthy — will pay.
