Social Security has also been expanded multiple times. Each expansion meant those already retired paid no added taxes, and those near retirement paid a bit more for only a few years. But both groups received increased benefits throughout retirement, increasing the unfunded benefits whose burdens had to be borne by later generations. Thus, each such expansion started another Ponzi cycle benefiting older Americans at others’ expense. Social Security benefits doubled between 1950 and 1952. They were raised 15 percent in 1970, 10 percent in 1971, and 20 percent in 1972, in a competition to buy the elderly vote. Benefits were tied to a measure that effectively double-counted inflation and even now, benefits are over-indexed to inflation, raising real benefit levels over time.
