I take it all back. Social Security isn't a Ponzi scheme. It's just an investment scheme that uses new investors to pay promised returns.
The money is "invested" with the plan administrators, who are $31 trillion in debt with no way to repay it and no intent to try.

It is a Ponzi scheme. Let anyone who want to opt out, opt out of taxes and future benefits. With or without Medicare, either way. If it's not a Ponzi scheme, what's wrong with that?
