Beyond that little detail, using your definition (and lewislynn's - ooohh you're in with it now!)...
Using your definition, today's income tax refunds are entitlements too.
Are you going to tell this forum that income tax refunds are entitlements?!
If it were an entitlement, there would be an appropriations bill, by law. There isn't one.What law?
No for two reasons. First you are not required to submit that money. Second, that is your money you paid. Under the fair tax, you are obligated to pay extra sales tax, and it is not neccessarily your money.
