World isn't even run by anyone, that's the hilarious bit. Billionaires just got lucky or inherited. They have no more ability to run a company or world than you or I.
What they do have are ancient systems of power and authority that let them claim the right to prey on us. They don't directly control it, they just inherited these too. And they don't need conspiracies - they just need people desperate to be like them.
Funny thing is they have no idea how vulnerable they truly are. How many of the exploited work for them, can get close to them?
Ever read White Tiger by Aravind Adiga? Worthy book.
