A tax rate reduction should mean a tax revenue increase.

True - IF, and only IF, you are on the correct portion of the laffer curve. Are you certain we are on the right side of the curve? Estimates for the "optimal" rate vary wildly - up to 80%, even. If you cut them too steeply without cutting spending, then you'll rack up enormous deficits as the efficiencies gained in the tax system won't be able to catch up to the initial loss in revenue. In 4 years spending has increased 32.7%, and revenues have only increased 7.6%, not even equal to the rate of inflation. The on-budget deficit is still near $500 billion. That's pathetic.

There are two different issues, both are important.

First, how to increase tax revenue.

Second, controlling spending.

This thread title deals with the first point :

Post # 11 addresses the first point :

The four years of tax revenue has been up because of the tax RATE decrease.

Likely the fifth year will produce another increase of revenue.

That is how we know that we are not on the left side of the curve.
