Lower interest rates is a laughable arguement. Interest rates and money supply is controlled by the fed. If all your rosey economic predictions came true, the fed would be forced to tighten the money supply and raise rates. Again, the pointie headed professors are clueless. Well educated, but clueless.
Anyone who believes the Federal and State governments can actually collect 30% sales taxes on every transaction is either delusional or an ivory-tower professor from a second-rate school.
Only short term interest rates. You'll notice that in 2004 the Fed raised short term interest rates 3 times and long term interest rates (mortgage rates) ended the year the way they began, at historic lows. Long term interest rates are more susceptible to inflation factors. The NRST is inflationary in that it tacks on 20-30% to prices over and above the pre-bate but it adds purchasing power in the form of higher take home wages. It would be interesting to see from a macroeconomic standpoint the effect of having food, water, warmth decling in price while life's little luxuries are increasing. I don't think there's ever been such a scenario.
