The not-so-great Warren Buffett - Greg Mankiw: "A master of tax avoidance." "Warren Buffett has an op-ed in today's NY Times on one of his most popular themes: The rich should pay more in taxes.

But on closer examination, one realizes that Mr Buffett never mentions doing anything to eliminate the tax-avoidance strategies that he uses most aggressively."
