Earlier quoted context omitted.
SS has collected trillions more than it has paid out. To deal with the post baby boom reduction in the work force. A true Ponzi scheme can't be stable over hundreds of years but SS could be. PS: I would like to see SS start at ~75 which seems to be the time when most people are incapable of meaningful work. And it's the age where most people who retired young start having major problems with their savings keeping up…
A Ponzi scheme is an investment system where the payout of current investors comes from the payin of future investors. That's the definition of ponzi. Does SS meet that definition or not? If so, it's a Ponzi scheme. The fact that it lasted longer than other historical Ponzi schemes does not change it's nature.
SS does not hide the fact that it pays money from dead investors to the living so it's not fraudulent. It does use some money from new investors to payout money but so does life insurance.
PS: While some people get far more out of SS than they pay in many people got zero benefits. With a SS their will would still "own" their money but with SS it diapers into the void. I don't mind calling SS a period scheme, but a lot of 22 year old's are going to die before their 60's so the math can work out just fine.
