Excerpt: "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. Nothing is invested. The money taken from you was spent by government that year. Right away. There's no trust fund. The plan is unsustainable. Medicare is worse."
