Of course, increasing the marginal rates will take more money out of the economy and hurt other areas such as businesses.
As far as the 2% are concerned, do you disagree with the CBO estimates as to how much additional revenue would be raised by going back to the Clinton rates?
No, you do not understand the Laffer curve. What you are saying that decreasing rates reduces revenue, Historically that is not true.
If your contention is we are to the LEFT of the Laffer inflection point then make your case, try anyway.
