Heck, i'd be fine with a slow transition into a fair tax to see how it'd work... however i still think it'd be best to keep a no deductions version of the income tax that just takes your money based on your paygrade for stabilties state. As a sales tax seems extremely unstable. Sure you see the money invested in stocks EVENTUALLY but if the investors are any good that's like 20-30 years from now, unless buying new stocks would have a tax to it. (or selling stocks.)
But stability can be another one of the items to hit down the rode.
