USD: When will it stop... falling?

[Final-Fan]

"The primary result of tax cuts is decreased tax revenue."

Let us explore my alleged tautology in more depth. I shall use your definition of "tax cut".

0) There exists a tax base paying a certain tax rate, creating tax revenue. Tb * Tr = Tv'
1) A drop in the rate of taxes to an existing tax base causes a drop in tax revenue. T(r-x) * Tb = Tv''
2) The lower tax rate encourages greater production and investment.
3) Greater production and investment creates greater wealth, and thus a greater tax base. T(r-x) * T(b+y) = Tv'''
4) You say that the increase in tax base will overcome the decrease in tax rate to create greater tax revenue than would otherwise have existed. Tv''' > Tv' (assuming an otherwise static universe)

(1) is the primary [edit] result of the tax cut. (2) [edit] is secondary; (3) is an indirect result, as is (4) if it happens at all.

Therefore, my statement has not yet been shown to be not a tautology.

P.S. I also want to apologize for my earlier tone. I would not regret speaking to Timmah!'s ilk that way, but you were undeserving of that scorn.

P.P.S.  Just to be completely clear, the fact that (2) is secondary does not necessarily speak to its importance in the view of the tax cutter.  It is secondary in the way that the creation of a vacant lot is a secondary result of demolishing the building that was on that lot.  (The first result, of course, is that the building is now a pile of rubble.)
