Ever notice how quiet they are about the illegal alien portion of the underground economy???
That's many billions of $$$ evaded right there in one fell swoop. Throw in the foreigh tourists (about 50 million in CA last year according to one article I saw), and pretty soon you have some big bux - all being evaded and/or not paid right now. It would be tax revenue under the FairTax.
Right. But how would the politicians control things with the IT? They wouldn't. That's why the left hates it.
