Two viable alternatives, Flat Tax & Fair Tax, and two viable debates. So do a test market for each. Select two similar states for each (no state income tax, with state sales tax, with approximately the same population, and employment rate). Since the Fair Tax is 'inclusive', it wouln't appear on a sales ticket any more than the flat tax. Run both models for 24 months, and then decide which would work the best. Pundits have no clue, and neither do you Dan, so use your influence in a constructive way and make this happen.
