Opponents of hiking benefits argue that typical seniors are actually doing quite well. New research from the Census Bureau, based on tax filings, found that seniors were actually doing somewhat better than data from surveys indicated.

While this was good news, there is an important qualification to this finding. By far the main reason that income for seniors was higher than previously reported is that the survey data missed a lot of income from traditional defined-benefit pensions. In other words, the Census study didn’t find seniors had hundreds of thousands in savings that were not being picked up in the surveys; the story was defined benefit pensions.

This matters because we know that traditional defined-benefit pensions are rapidly disappearing. This means that the picture of middle-class seniors retiring with little other than their Social Security to support them still looks right. The average benefit this year is just over $17,600, certainly not enough to maintain a middle-class lifestyle. For this reason, the modest benefit increase proposed by Larson is very reasonable.

Larson proposes to cover this increase, as well as the projected Social Security shortfall, by having a gradual increase in the payroll tax and applying the tax to very high-income workers. On the latter point, the income subject to the payroll tax is currently capped at just under $133,000. This means that someone earning millions of dollars each year would pay no more in Social Security taxes than someone earning $132,900. Larson’s bill would make wages over $400,000 subject to the tax.

His other change is an increase in the payroll tax of 0.1 percentage point annually, split between workers and employers. This increase would continue for 24 years, for a total increase of 1.2 percentage points on both the worker and the employer.

While this is a middle tax increase, it is much smaller than increases we saw in the decades of the 1950s, 1960s, 1970s, and 1980s. More importantly, if we can sustain decent wage growth, it is a tax that should be easy to bear.

After adjusting for prices, wages have risen 1.5 percent annually over the last five years. If we can continue this pace of wage growth, the Larson bill would take back much less than 10 percent of the pay increase in taxes. Of course, wage growth may not continue, but then our focus should be on getting decent wage growth, not blocking revenue needed for Social Security.

In short, this is a well-considered bill that would accomplish good for current and future retirees. Congress should move on it.
