The U.S. Securities and Exchange Commission was set up to combat fraudulent practices.
The SEC's Web site explains that "Ponzi schemes are a type of illegal pyramid scheme named for Charles Ponzi, who duped thousands of New England residents into investing in a postage stamp speculation scheme back in the 1920s."
It goes on to say, "Decades later, the Ponzi scheme continues to work on the 'rob-Peter-to-pay-Paul' principle, as money from new investors is used to pay off earlier investors until the whole scheme collapses."
A Ponzi scheme does not generate any wealth whatsoever; that is why it ultimately collapses.
