I couldn't agree more with Pete on the discussions of tax policy that are now occurring as part of the Republican primary campaigns. The Republican primary campaign almost always gets sidetracked by some inane proposal for tax reform. This year it is the 9-9-9. And now we have another version of the flat tax, as if the crushing irrelevance of Steve Forbes to the primaries in 1996 and 2000 were not an indication of how unproductive the discussion will ultimately be. What are the prospects that a Republican President would actually be able to implement such a change if elected? They are equal to the chance that Republicans will both retain control of the House and secure a filibuster-proof majority in the Senate in 2012. In other words, absolutely zero.
True. But you have to look at this through a different lens. In the modern Republican Party, tax policy isn't really about tax policy anymore. It's mostly just meant to be evocative, a demonstration that you're really, truly part of the family. So the crazier it is, the better. Nobody—least of all Republican voters—seriously expects any of these proposals to become law.
What's really mind-blowing, though, is the precise nature of the tax policies that rich Republicans have so thoroughly succeeded in adding to the canon. Middle-class conservatives have become completely convinced that "good" tax policies include a flat tax, lower capital gains rates, and repeal of the estate tax, all of which are designed to benefit the rich almost exclusively. It would be as if Democrats had somehow convinced Wall Street that the key to prosperity was higher taxes on yachts, private jets, and Hamptons getaways.
