Well, with the Income Tax, you can choose whether to work or not. I'd say they are about equal in "voluntariness".
That makes no sense whatsoever.
C'mon. Are you kidding?
Right now, if you work for someone else taxes are withheld immediately from your check. Under the FairTax, when you decide to spend your money, you will then be taxed. To a large degree you decide your tax bill and when it's paid, not the feds.
To imply that FairTax supporters are saying otherwise is less than honest and you know it. The Feds talk about a voluntary system, but neglect to follow that up with the consequences that you'll face for not volunteering.
