Having a world built by billionaires only works if you don't think about what being a billionaire means. Namely, how having enough money to take control of an entire country affects your view of yourself and the world around you. I can't see how I would not become a psychopath if I had billions of dollars. The ability to get rid of anything you don't like is just sitting right there. So I have to ask, in a world where we don't give people illegal drugs because it could cause them to become evil, why are we letting people have billions of dollars?
