Warren Buffett caused quite a stir last week. In a New York Times op-ed, he told Washington to stop "coddling" the super-rich.
He said that last year he only paid 17.4 percent on his taxable income, while employees in his office paid from 33 percent to 41 percent.
Buffett is a spectacular judge of value in the market, but his suggestion that the tax system is no longer progressive is a head-scratcher. His impressions clash with numbers published by the Congressional Budget Office (as Michigan economics professor Mary Perry noted on the Carpe Diem blog).
