While Social Security is not in a crisis, it does require periodic adjustments to make it work, as the economy and demographics of the population change. It can be made solvent with minor tinkering at the edges such as removing entirely the cap on payroll tax income or increasing the rate of taxation by small amounts or by lowering the annual cost-of-living increases in benefits or, in the worst case, by slightly reducing the benefits. We are not facing the catastrophe the doomsayers predict.
The major problem with Social Security is not with the retirement benefits part but with rapidly rising Medicare costs. Currently the Social Security tax (the part that goes towards retirement benefits) is 12.4% of income up to the cap, which is $102,000 for 2008. The tax rate for Medicare is 2.9% of your gross income. Your employer pays half of this 15.3% total, unless you are self-employed in which case you are responsible for the entire amount.
It is the Medicare costs that are already outstripping Medicare revenues and rising rapidly, and thus straining the government’s finances. But this is largely a health care costs problem, caused by the hugely wasteful profit-making health system that currently exists in the US that has resulted in per capita costs that are at least twice as much as the costs in other developed countries and yet produces worse results. Introducing a single-payer system like that which exists in France or Canada would result in savings, greater ability to control costs, and better health care overall. (See the series of posts on health care where these arguments are presented in more detail.)
