"Real-life Robinhood?" Really? I think its far more likely that he is a damn smart businessman. Consider this fact:
Buffet spoke out about keeping the Estate Tax, because, as he said, rich people need to pay more. In reality, the Estate Tax generates over $ 12 Billions dollars a year for big life insurance companies, which Buffet either owns stock in or controls.
If Buffet was a "real-life Robinhood" he would say repeal the Estate Tax (as it destroys jobs and small businesses) and make ME pay more directly.
Don't agree about the Estate Tax? Watch this video http://www.youtube.com/watch?v=Urvkfi134Ew and tell me how you figure.
