And entitlement is:
"... a government program providing benefits to members of a specified group ..."
The FairTax is not a government "program" but a tax law nor does it provide benefits to members of a "specified group" but basically to all citizens. Call it what you like however (since you've show that you will regardless of the facts). Demagogue away and mislead as many as you can who buy into your claptrap!!
If you don't think it's an entitlement, send the checks out for a few months then reduce the amount or discontinue them all together, then tell me it's not an entitlement.
