Quote from peilthetraveler:
The guys dad was obviously a financial genius. You would think he would've learned something from him. When you have access to someone worth 600 million dollars, you would think you would want to pick their brain as much as possible.
You probably got it wrong, the company was built by his brothers, hence they got 100m each, he and his father were just minority shareholders. they were lucky being related to this business at first place.
