> I don't really see any evidence that the poor are smarter than the rich.

This is attributable to survivorship bias. Poor people who make bad decisions either die in a gutter or die in a cell. Rich people who make bad decisions get golden parachutes and fail upward ad infinitum.

> If you think you are smarter because you are a "normal person" then I think you need to consider that everyone is dumber then they realize.

Firstly, to paraphrase Socrates, I fully own that I'm a dumbass, secondly the events of the past decade made it starkly clear that, yes, everyone is dumber than they realize, and now I'm forced to realize it, too.
