Oh, no, not a Ponzi scheme, no siree, and how dare any of those nasty presidential candidates say so:
There were only 1.75 full-time private-sector workers in the United States last year for each person receiving benefits from Social Security, according to data from the Bureau of Labor Statistics and the Social Security board of trustees.
That means that for each husband and wife who worked full-time in the private sector last year there was a Social Security recipient somewhere in the country taking benefits from the federal government.
Pretty simple demographic reality, but even supposedly conservative Republican candidates feel free to jump all over the one person willing to acknowledge it, and then even that person backs down in the face of the opposition. Doesn't say much about our current ability to face the truth.
