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.
The problem that we have with tax policy is that we don't raise enough revenue to cover our expenditures, not the particularly ways we choose not to raise that revenue.
