Warren Buffett doesn't want to pay taxes. He wants to keep avoiding paying taxes on his billions. Presumably Buffett's billions allow him to hire a competent tax lawyer. Thus Warren Buffett knows that the only form of "fair taxation" , the only vehicle which would (ever) result in the billionaires paying their fair share of taxes is a flat wealth tax. The obvious difference between income taxation and wealth taxation is that with wealth taxation the billionaires can no longer permanently hide their billions from taxation. In fact, they can't hide anything at all. No more free ride. The great irony with Buffett's duplicitous taxation proposal is that the millionaires have always chosen to align themselves politically and economically with the billionaires. They were (supposedly) on "the same team." Now the millionaires can see for themselves what a flawed assumption that was. As we see today, when confronted with the threat of (perhaps) paying something remotely resembling fair taxes themselves, the billionaires have decided to throw the millionaires under the bus. They can pay "fair taxes," while billionaires like Buffett keep laughing all the way to the bank (they own). As I've observed in the past, it is the very wealthy, themselves, who have spent decades pounding the table demanding a Flat Tax. They tell us that a Flat Tax is the only path toward "fair taxation." Of course what the very wealthy wanted was a flat income tax, where their huge wealth-hoards would continue to remain untouched while their tiny increment of income would be taxed at the same, low rate as the Little People -- for whom income is all they have. In fact a "flat tax" is the basis for the most fair form of taxation, but it can only be a flat wealth tax. Note that the same argument which applies against income taxation is even more applicable regarding heinous "consumption taxes," currently being advocated by many brain-dead economists. Knowing that the Little People can't have any more income taxes squeezed out of them, these Rocket Scientists propose taking more out of their pockets via sales taxes -- as if simply calling the tax by a different name will reduce the economic pain (and carnage) from such tax increases.
