This is full admission by our Treasury Secretary that the Us financial system is a Ponzi Scheme
Ultimate unraveling of a Ponzi scheme
The catch is that at some point one of these things will happen:
1. The promoter will vanish, taking all the remaining investment money (minus payouts to investors already made).
2. Since the scheme requires a continual stream of investments to fund higher returns, once investment slows down, the scheme will begin to collapse under its own weight as the promoter starts having problems paying the promised returns (the higher the returns, the greater the risk of the Ponzi scheme collapsing). Such liquidity crises often trigger panics, as more people start asking for their money, similar to a bank run.
