Is a newly built house considered a new product but a home with a previous owner not? What about used cars? What about medical bills? Insurance?
No "FairTax" (I loathe that biased name) advocate can get around the regressive nature of a flat sales tax. Not to mention the sticker shock of a 20% or higher sales tax on almost everything. It's absolutely brutal to low income taxpayers. It will never pass, and I wouldn't want it to.
Go read the legislation and quit making unsound and unfounded comments!
