Simmons does say something I disagree with. He says that you should be taxed at 15% because if you invest you could lose. This is not what happened in the USA. The bailout of companies that engaged in risky practices was supported by the American taxapayer when they lost money. The whole "too big to fail" attitude had an effect.
It is not quite true that you could lose everything. In the US version of capitalism, companies get to privatize their profits and socialize their losses.
