Are you telling me that, if I set up an investment portfolio where I deposited participants money into my savings account, it would be legal as long as I told them about it and did not promise excessive returns? Would it also be legal if I then took new investors deposits and used them to pay higher than normal returns to older investors, as long as I continued to be open about what I was doing? Would that be a Ponzi scheme, or would it be something else?
Everyone that is trying to argue that SS is not a Ponzi scheme is focusing on it being fraudulent in some way. My guess is that if any private individual actually set up something like SS, even if they were completely honest about what they were doing, the government would have a serious problem with it. Do you agree with me, or disagree?
A Ponzi Scheme has to be fraudulent by definition. If there is no fraud, there is no Ponzi Scheme.
You as a private citizen cannot take other people's money and deposit that money into your account. But the government doesn't do that with SS either. You have a SS account, and your account is credited and debited based on your contributions, interest earned and redemptions. A mutual fund does the same thing. SS is like a giant government bond mutual fund, where participants are making deposits, earning interest and redeeming funds. As a participant in a mutual fund, you have an account, and your account is debited and credited base on your contributions, interest earned and redemptions. The economics, if not the operations, of SS works in the same manner as you owning units of a government bond mutual fund.
Bad system? Yes.
Ponzi Scheme? No.
