Under the inappropriately-named "fair tax," the old phrase of "Your papers, please" will soon become "Your receipt, please." And don't think the government won't start keeping tabs on what you purchase. Governments practically live to accumulate information on the citizenry.
There are tens of millions of people not paying any income tax NOW. The way I see it, there will always be corruption and the same amount of money will flow into the government pockets, it will just be collected differently.
Quite to the contrary, the bill contains requirements that individual persons must produce documentation if they suspect you owe tax.
