Phasing it in - No way we can just switch overnight but if we institute a small percentage national sales tax, then slowly increase it as the income tax is done away with it could be implemented.
Sounds good, but can you name one federal govt program that was eliminated when it was no longer needed?
Remember, the fed was once a watchdog for the upper limits on the usery percentage on consumer credit. They raised the ceiling "just to get us through a rough spot." Then they solemly swore that they would reduce them once the inflation rate was lowered. "Right away". Of course the states individually jumped on that bandwagon. That was when Jimmy Carter was president, and we were all freaked out at 18% credit card interest ceilings!!!
They're (govts in general) not historically capable of phasing anything. It would require fiscal restraint. But they're damned good at raising things to heretofore unimaginable heights.
Always remember, the two goals of any elected office holder are:
1. Get elected.
and after achieving #1,
2. Get re-elected.
That's it. It's that simple.
The Bush tax cuts qualify as a modern day miracle in my estimation.
MSH, I think that you're confusing Fair Tax with National Sales Tax. They're completely different animals, from what I understand anyway.
