Yes but THEIR incomes aren't no matter how much you spin and spin and spin.There are two criminals in the activities you list, the seller and the buyer. Currently the buyers are taxed and the seller don't. Under the FairTax sellers would pay and the buyers don't. It's a wash!
I made that point a hundred times. It's either stupidity, stubborness, or just brainwashing, but they can not concede a point no matter how obvious it is.
