Ponzi! Ponzi! Ponzi! There, I said it. To the extent people believe there are trust funds with their names on them, Social Security is absolutely a Ponzi scheme. So is Medicare. People need to hear it.
Many people think that when the government takes payroll tax from their paychecks, it goes to something like a savings account. Seniors who collect Social Security think they're just getting back money that they put into their "account." Or they think it's like an insurance policy -- you win if you live long enough to get more than you paid in. Neither is true.
