Republicans aren't interested in reform, that's just their latest fig leaf for cuts in service of starving government of revenue and making the rich more rich. There are plenty of places to reduce waste (the pentagon, per their own report) and reduce targeted deductions (capital gains and dividends, which provide income mostly to the wealthy, unlike us poor saps who work for our wages). They don't want "fair" tax any more than they want a fair society, they want a country where the ruthless and greedy aren't stymied by social obligation.
