Business and markets run on trust. The less trust you have the more overhead you have to verify that every claim your counterparty makes is true. That's expensive and means some worthwhile things become impossible to do profitably. It's a tradeoff and I think in general the US finds a good spot between regulation and ease of doing business, and the rest of the world benefits from it too.

There are failures of course, but most of the big ones recently have been in private markets not the public ones.
