It's a straw man:en.wikipedia.org "The U.S. Social Security Administration provides the following response[16] to the "Ponzi scheme" accusation as applied to a pay-as-you-go system like Social Security: There is a superficial analogy between pyramid or Ponzi schemes and pay-as-you-go insurance programs in that in both money from later participants goes to pay the benefits of earlier participants. But that is where the similarity ends. A pay-as-you-go system can be visualized as a simple pipeline, with money from current contributors coming in the front end and money to current beneficiaries paid out the back end. So we could [imagine] that at any given time there might be, say, 40 million people receiving benefits at the back end of the pipeline; and as long as we had 40 million people paying taxes in the front end of the pipe, the program could be sustained forever. It does not require a doubling of participants every time a payment is made to a current beneficiary. (There does not have to be precisely the same number of workers and beneficiaries at a given time--there just needs to be a stable relationship between the two.) As long as the amount of money coming in the front end of the pipe maintains a rough balance with the money paid out, the system can continue forever. There is no unsustainable progression driving the mechanism of a pay-as-you-go pension system and so it is not a pyramid or Ponzi scheme. If the demographics of the population were stable, then a pay-as-you-go system would not have demographically-driven financing ups and downs and no thoughtful person would be tempted to compare it to a Ponzi arrangement. However, since population demographics tend to rise and fall, the balance in pay-as-you-go systems tends to rise and fall as well. During periods when more new participants are entering the system than are receiving benefits there tends to be a surplus in funding (as in the early years of Social Security). During periods when beneficiaries are growing faster than new entrants (as will happen when the baby boomers retire), there tends to be a deficit. This vulnerability to demographic ups and downs is one of the problems with pay-as-you-go financing. But this problem has nothing to do with Ponzi schemes, or any other fraudulent form of financing, it is simply the nature of pay-as-you-go systems. "
