If that leftist freak Buffet really wants to pay more of his money to the US Treasury, NOTHING AT ALL stops him from writing a check and dropping it in the mail.
From presidential primary debate on 4/16/08:
Charles Gibson: "...And in each instance, when the rate dropped, revenues from the tax increased. The government took in more money. And in the 1980s, when the tax was increased to 28%, the revenues went down. So why raise it at all, especially given the fact that 100 million people in this country own stock and would be affected"?
Obama: "Well. Charlie, what I've said is that I would look at raising the capital gain tax for purposes of fairness".
