I rather think that depends upon what you think "small" might be. I was using the poster's number of 30%.
Again, for the fifth time, according to the IRS, Business Taxes are under $200 Billion. According to NIPA, US consumption is at about $8 Trillion. Only the fuzzy math of Fair Taxers tell us that $200 Billion is 30% of $8 Trillion. No one can refute these facts. From what I can tell, you are about $2.2 TRILLION short from telling me where all these costs reductions are coming from so businesses can lower their prices to offset your 30% tax.
