If I have saved a million dollars and been subjected to the current tax system on that million dollars and then FAIR Tax is implemented and I spend the million dollars, am I going to be taxed again on that million dollars or not?You are. Economist consider switching to a sales tax a tax on current wealth. That million would be your current wealth.
IF it's in a retirement plan, you never paid income taxes on it in the first place. Now, do you really have a million dollars saved or are you just blowing smoke?
