It is becoming clear to me that Americans don't know how to do math very well or there would be overwhelming support of the fair tax. It is also clear that the governement is very clever at hiding how much they truly are taxing us, and how many people aren't paying taxes. i.e. all those brits that are coming here to buy stuff due to the farvorable exchange rate.
I don't so much worry about the black market it can't become much worse than all the tax cheats there are now.
My biggest fear is that they won't eliminate property tax under this plan.
