Little is as distressing in the public discourse as the linking of the financial problems of Social Security and Medicare. It is a favorite ploy of the deficit hawks to claim we must reform our entitlement programs without distinguishing between the two. I am at a loss to explain this. It is clearly ideological -- small government no matter who gets hurt. But Social Security payouts will rise from roughly 5 percent of GDP to 6 percent at worst down the road, while Medicare will rise by much more.
Nevertheless, poorly educated pundits, willing to believe the self-proclaimed centrist view that we cannot tax our way to solvency, demand Social Security reforms from selfish baby boomers. Monique Morrisey of the Economic Policy Institute does good work on this. Moreover, there is even a detailed Senate report on the issues that requires only a little updating. Maybe journalists should read it before they write about the subject. Its title is rather self-explanatory: "Social Security Modernization: Options to Address Social Security Solvency and Benefit Adequacy from the Senate."
First, remember that Social Security provides nearly 60 percent of the elderly more than half of their income. Seventeen percent receive all their income from Social Security, mostly households headed by elderly women. Most remarkably, and it would be nice for young people to register this, the poverty rate measured by the federal government for the elderly was 35 percent in 1959. As Social Security became more generous, it was reduced to 10 percent, about where it stands today. This is one of the great social achievements of our time.
Now for that future financing gap. It's true that payroll taxes won't cover all the benefits to be paid in 25 years or so, as the ratio of the elderly to workers rises and life expectancy grows. But a more important and lesser known cause of this future gap is inequality of income. Tax revenues are reduced because incomes have stagnated for so many. Due to an earnings cap above which taxes are not collected, now about $110,000 a year, combined with the rapid rise of incomes for high-end earners, some 17 percent of aggregate earnings are not covered by the payroll tax. In 1980, only 10 percent were not covered.
But the solvency gap, as we might call it, is not very large, amounting to only 2.67 percent of GDP. How can that be closed? Pretty darned easily. For example, the cap can be eliminated. This would close almost the entire gap if high-end earners do not receive higher benefits. It will still close four-fifths of the gap if they do.
Another way to close the gap would be to raise payroll taxes by 1.1 percentage points, from 6.3 percent to 7.6 percent. This would entirely close the solvency gap. Or the tax could be raised by a little more than 1 percentage point in 2020 and another percentage point in 2052, also eliminating the solvency gap.
A combination would also work. If the cap were raised to cover 90 percent of all workers, for example, it would close about 25 percent of the gap. Thus, a tax increase to close the rest would be smaller. Alternatively, the payroll cap on employees could be limited to 90 percent and eliminated altogether for employers. This would just about eliminate the gap.
There are many other options and permutations, but any claim that a pragmatic increase in taxes cannot close the gap is utterly wrong.
Let's also keep in mind that Social Security solvency is based on a 75-year forecast. Any increase in the rate of growth over what is expected will reduce the gap significantly. Now to really be pie in the sky, there is also the possibility of investing in the economy to enable it to grow faster—investing in infrastructure, education, and so on. More equality of income would also reduce the solvency gap. For those eager for major benefit cuts because we can't be sure about growth, well, they can be quite modest if coupled with tax increases. But they are not necessary now!
Medicare is a different issue. In sum, the nation pays about twice as much for what it gets from health care than it should compared to other countries. This is the domestic problem of our time. I think Obamacare may start us down the road to control these costs, especially if we ultimately add a public option at something like Medicare rates. That's where pundits and deficit hawks should focus their attention. Instead, they like picking on Social Security, our single greatest achievement. Why?
