His money is in a charitable remainder trust, and it doesn't look like he's about to suddenly change his spending patterns or habits. He can say whatever he wants, and claim who knows what, as it won't change much of his personal wealth. His business interests will adjust and/or adapt, and will lobby for some other type of preferential treatment to keep raking it in.
Just because he's stinking rich doesn't mean that we have to listen to EVERY word that he says. Maybe he should just go back on CNBC and answer some more stupid questions, like where he gets his hair cut and how much it costs, if he wants to inflate his ego some more.
Unfortunately raising the tax on the rich isn't going to be enough to balance the budget. It will certainly help, but it's not a cure all. I don't think a 30% tax rate on investment income over 1 million dollars is going to be too much of a hardship for anyone.
