Insanity is doing the same thing over and over and expecting a different result.
They can increase the prebate 20% (in an election year, of course) without increasing the Fair Tax rate by simply declaring that the new poverty level is now 20% higher. Before you know it, poverty will be defined as income of $100,000 or less.
The proposed prebate is nothing more than a vote getter. As I demonstrated, it's not necessary to "offset" taxes for the poor. If they use it that way once, they'll use it that way again.
It works just fine in, what, 43 states. Who's refusing to admit the truth?
