Changing the tax code to one that goes up on auto-pilot (the FairTax) is not going to change the desires of politicians to buy votes. And, once they see that they have not enough money coming in, they will put a income tax surcharge on those “rich” people making more than say $100k per year. This will get them votes from 80% of the population, at the expense of the 20%. And they will do this on top of the 40% or higher FairTax sales tax (when expressed as a normal sales tax).
Polticians spend to buy votes. Plain and simple. The FairTax does nothing to stop that basic fact of politics. Nothing.
HOW? they won’t even know how much people make!
