This guy decided to get into politics like 5 months ago and is now the second most powerful person in the world purely by dint of being extremely wealthy. He bought the US government and it was apparently a bargain at $250M.
The system has been broken for a while, but that certainly made it clear. Reagan set in motion what led us to the current wealth disparity and Citizens United didn't help the state of things.
Actually, 44.28bn when you include twitter acquisition. Still a bargain.
