Generating more cash for Congress to steal and squander is just wrong. We need to strangle the cashflow, because these parasites just will never get it. It's not their money, and they can buy votes, so why would they stop as long as we find ways for them to steal more of it?
You are correct, spending cuts are just as important as tax cuts, but given a choice of one - I'll take the tax cuts which might force the starvation gambit.
As I think I once saw - the fiduciary pecking order is thus:
Spending one's own on one's self
Spending one's own on other's
Spending other's on one's self
Spending other's on other's
As you state - Govt has the LEAST incentive possible in responsible spending of the people's money.
The whole point of the article was that cutting taxes increases the cashflow from which Govt's take, evan at a smaller percentage rate = more revenue.
