Using the term "ponzi scheme" is just a way to falsely undermine it. You can take a Savings and Loan and if the officers are stealing from the saver accounts, it's most likely going to fail. It does not mean that Savings and Loans are ponzi schemes or are doomed to failure. As to the second part, did average people have nest eggs prior to SS? My understanding is that SS came about because business-men took the country down during the Great Depression, kind of like they did recently! That the
New Deal was created to give the working class a chance. Why would they need a chance? Because Capitalism when left to its own devices, becomes completely unbalanced enriching the few, and abusing the many. When overall society if considered, raw unregulated Capitalism is inequitable.
My impression is that average people did not make that much prior, so what part of American culture was destroyed? And gee, the New Deal promoted labor unions. Why on earth would they do that? The work of a bunch of commie-socialists?
