The Great Social Security Debate, Proposition 1: Of course it's a Ponzi scheme.
In a Ponzi scheme, the people who invest early get their money out with dividends. But these dividends don't come from any profitable or productive activity -- they consist entirely of money paid in by later participants.
This cannot go on forever because at some point there just aren't enough new investors to support the earlier entrants. Word gets around that there are no profits, just money transferred from new to old. The merry-go-round stops, the scheme collapses and the remaining investors lose everything.
Now, Social Security is a pay-as-you-go program. A current beneficiary isn't receiving the money she paid in years ago. That money is gone. It went to her parents' Social Security check. The money in hercheck is coming from her son's FICA tax today -- i.e., her "investment" was paid out years ago to earlier entrants in the system and her current benefits are coming from the "investment" of the new entrants into the system. Pay-as-you-go is the definition of a Ponzi scheme.
So what's the difference? Ponzi schemes are illegal, suggested one of my colleagues on "Inside Washington."
But this is perfectly irrelevant. Imagine that Charles Ponzi had lived not in Boston but in the lesser parts of Papua New Guinea where the securities and fraud laws were, shall we say, less developed. He runs his same scheme among the locals -- give me ("invest") one goat today, I'll give ("return") you two after six full moons -- but escapes any legal sanction. Is his legal enterprise any less a Ponzi scheme? Of course not.
So what is the difference?
Proposition 2: The crucial distinction between a Ponzi scheme and Social Security is that Social Security is mandatory.
That's why Ponzi schemes always collapse and Social Security has not. When it's mandatory, you've ensured an endless supply of new participants. Indeed, if Charles Ponzi had had the benefit of the law forcing people into his scheme, he'd still be going strong -- and a perfect candidate for commissioner of the Social Security Administration.
But there's a catch. Compulsion allows sustainability; it does not guarantee it. Hence ...
Proposition 3: Even a mandatory Ponzi scheme like Social Security can fail if it cannot rustle up enough new entrants.
You can force young people into Social Security, but if there just aren't enough young people in existence to support current beneficiaries, the system will collapse anyway.
When Social Security began making monthly distributions in 1940, there were 160 workers for every senior receiving benefits. In 1950, there were 16.5; today, three; in 20 years, there will be but two.
Now, the average senior receives in Social Security about a third of what the average worker makes. Applying that ratio retroactively, this means that in 1940, the average worker had to pay only 0.2 percent of his salary to sustain the older folks of his time; in 1950, 2 percent; today, 11 percent; in 20 years, 17 percent. This is a staggering sum, considering that it is apart from all the other taxes he pays to sustain other functions of government, such as Medicare whose costs are exploding.
The Treasury already steps in and borrows the money required to cover the gap between what workers pay into Social Security and what seniors take out. When young people were plentiful, Social Security produced a surplus. Starting now and for decades to come, it will add to the deficit, increasingly so as the population ages.
Demography is destiny. Which leads directly to Proposition 4: This is one Ponzi scheme that can be saved by adapting to the new demographics.
Three easy steps: Change the cost-of-living measure, means test for richer recipients and, most important, raise the retirement age. The current retirement age is an absurd anachronism. Bismarck arbitrarily chose 70 when he created social insurance in 1889. Clever guy: Life expectancy at the time was under 50.
When Franklin Roosevelt created Social Security, choosing 65 as the eligibility age, life expectancy was 62. Today it is almost 80. FDR wanted to prevent the aged few from suffering destitution in their last remaining years. Social Security was not meant to provide two decades of greens fees for baby boomers.
Of course it's a Ponzi scheme. So what? It's also the most vital, humane and fixable of all social programs. The question for the candidates is: Forget Ponzi -- are you going to fix Social Security?
