Here is my point: it is clear in the minds of many that tax cuts in and of themselves do not, in the short run (i.e., first order effects), increase tax revenues. I agree with this view in the general sense. However, as you can see from your own citations that there are those who disagree, especially when measuring over the longer term. Of course it's not unanimous; nothing is ever unanimous with economists.
As you saw from my previous post, analysis of IRS data over the interval 1955-2008 generally, though weakly IMO, supported the supply-side proposition. More specifically, that analysis supports the proposition that spending growth is the primary culprit for our current deficit situation rather than tax cuts. (Note: you might have been better served by more examation data over varying starting and ending dates, as indicated by one of your cites. Just my opinion.)
Furthermore, in another post, I cited a study of numerous previous fiscal consolidations, their causes and their cures. The far and away dominant successful strategy was to cut spending by a lot and raise taxes by modest targeted amounts. The successful strategies did not employ 'soak the rich' tax increase. You can refer to the cite for specifics, or if you wish, I'll post them-just let me know.
To summarize, my reading and study strongly suggests to me that spending is the dominant problem, while tax rates play a stronger but lesser role. The single most important tax rate is the overall effective tax rate, not the highest marginal rate. If true, that means that for federal income taxes, the structure of brackets and the allowed deductions become all-important. State and local taxes, FICA, and all the other components that are part of one's total taxable bite must be considered as well.
Out of time...more later.
