Dictator 100%. If money is no object I would live in a complete hellhole where I could essentially have whatever I want at all times by paying the right people. I'd be like the villains in those fucking Raid movies from Indonesia.
Third world because I'd not be rich..I'd be alpha omega rich thus can own the country and turn it into a safe haven for racism...THAT IS THE PLAN OF THE CEO OF RACISM MUHAHAHAHAHA
At this point inflation is reaching such ridiculous levels in the first world that at some point being 'rich' in a relatively disconnected third world country would probably leave you richer than if you were what is considered rich in a random "first world" country. Especially seeing the way the US is going.
