They are some greedy bastards!
Greed is basically what makes these people become so successful. You don't get that far by giving away money.
I just watched a movie the other day about the way the US is with how far off the rich is from the 99%. The 1%, like 400 or so people have half of the US's wealth. The reason our economy is this way, is because so many of these rich people don't put any money back, they save. So yeah, this reminded me of that.
