I think even the folks at Brooking would agree that they don't really know how much the folks at various income levels would wind up paying. Their work looks like it depends on fairly static analysis--is there maybe a chance that people might modify their behavior based on the new tax rules?
At any rate, if we don't like the way the burden is distributed, it's simple enough to shift the curve by modifying the top rate by a few points and changing the income level of the rate change. That's simple (but important) stuff. The more fundamental questions:
- Does the plan get the "big stuff" (e.g. what counts as taxable income?) right?
- Does simplification of the tax code have inherent benefits as a standalone goal? I think it does. It enhances flow of capital to where it can be most efficiently utilized (which increases productivity/GDP), it increases transparency and it increases faith in the fairness of our tax system.
