No doubt that very rich men do give back to their country, this is good. But what is being questioned is how these same men, once they are much older and not going to play the betting game for self gain anymore, decide to do what is good for the people instead of what is good for them. So why T-Boone did not think of American oil dependence to other countries 40 years ago when he was rich? Why did he place his bets and make huge money on oil, and nothing wrong with that, but why then wasnot he thinking about the country then, and preserving its capitol with wind and natural gas? He was not concerned with trillions going outside the country for oil then. He was concerned about being on the right side of the bet. That is a good trader. But now he is concerned for the country as a whole? This is what people are questioning.
Who knows, maybe he has the forsight to see the future is in wind and natural gas, so he puts his money in that, and places his bets for the future of his children and grandchildren. Like Buffet, his time is over soon.
