Every child starts out thinking, "if I was in charge, I could fix this. It's so simple!"
Then you actually see that when you make bad choices, you or others get hurt, and you realize that you don't always know what's best.
But these guys never get hurt, because they have the money to be shielded from it, so they end up being these delusional wrecking ball assholes, who think they know better than everyone else and don't need anyone else's consent (I.e. votes) to make whatever overly simplistic or authoritarian changes their underdeveloped brains concoct.
