I don't know where you get your information on the FairTax, but it is obvious that you are misinformed about it. The enforcement mechanisms of the FairTax are already in place in 45 or so of the 50 states, so how do you get that it would expand the Government.
Two other comments you made here are also wrong, 1. People have been cheating on taxes ever since taxes have been collected, and 2. There is no such thing as taxes that are not a drain on the economy.
