While the FAIRtax is a potentially good idea, I prefer a flat tax of 15%. First $35,000 is tax free and then you pay 15% on everything after.
Flat tax is still on income and that is my problem with it ... complex interaction with the IRS.
I would only favor the Fair Tax if it involves a constitutional amendment forbidding congress from ever passing any form of income tax ever again.
A flat tax would last one, maybe two congressional terms and then the asshats would start tinkering with it all over again.
Their power to grift lays in their power to tinker with the tax system and they know it.
Sounds about like the prebate. A $35000 exemption on income tax is probably about the same as a prebate to exempt $35,000 of spending.
