For the record, I did not intend to start yet another forum war over tax exemptions; I just wanted to make the point that the real cause for our complex tax code is exemptions and deductions, not marginal tax rates. Oh well, unintended consequences.
On the topic of tax reform, I am in favor of trimming down our forest of deductions, but as was mentioned above, wiping them out entirely, just as with earmarks, would have substantial unintended consequences. Also, to the extent any major changes are made, they need to be phased in to minimize disruption.
In the big picture, I favor a much more progressive tax code, which includes lowering taxes on most Americans while raising marginal taxes on the high end. When I say “make the taxes more progressive” I don’t mean “only on the high end” - I mean lower the low end, raise the high end. As part of that, I feel like reasonable deduction reform is a good idea.
