Is Social Security a Ponzi Scheme

In the aftermath of the Madoff implosion, quite a few people have pointed out the parallels between a Ponzi scheme and Social Security. Arnold Kling, whom I respect, has written:
I’ve been thinking that Madoff is a perfect analogy for the public sector. The government gives people money, which it expects to obtain by taking the money from people in the future. Even the Center on Budget Policy and Priorities, not known as a right-wing organization, sees the U.S. fiscal stance as unsustainable (pointer from Ezra Klein via Tyler Cowen)—in other words, a Ponzi scheme.

Other people have gone farther. Paul Mulshine of the New Jersey Star Ledger wrote a column entitled “The Ponzi scheme that Baby Boomers are waiting to cash in on.” And Jim Cramer has called Social Security the biggest Ponzi scheme in history.

Superficially, these critics have a point, and there is a parallel between Social Security and a Ponzi scheme. But on a fundamental level, they are very wrong, and it’s worth explaining why.

First, the parallel. Social Security taxes current workers to pay Social Security benefits for current retirees. In other words, the new entrants into the Social Security system, the young workers, pay off the previous entrants, the older workers. And despite the fact you have a Social Security “account”, there is no necessary link between what you paid into the system in taxes, and what you receive.

That’s very similar to the structure of a Ponzi scheme, where new investors pay off the original investors. As long as enough new ‘victims’ are brought into the scheme, it keeps growing and growing. But when the new investors runs out, the Ponzi collapses. Analogously, the slowdown in population growth puts pressure on Social Security finances.
