If you will go to the site on the 999 plan, what you describe is step 2. He is basically saying this is a better system, but we cannot get there all at once.
I would still rather we go straight to a flat tax and not go with the sales tax.
I’d be VERY happy with the Fair Tax, but not without a constitutional amendment.
That said, I still like Cain and the last thing I’d expect him to do is put up a plan like 9-9-9 and then get wishy-washy on it before any legislation had even been written.
