I get the same prebate whether I spend up to the poverty line or not. I could spend less and still get the prebate. How is it a refund if I get more than I paid? My kids didn't pay any sales tax, they get a prebate. LOL!
An entitlement is a different thing
1 a: the state or condition of being entitled : right b: a right to benefits specified especially by law or contract
2: a government program providing benefits to members of a specified group; also : funds supporting or distributed by such a program
Sounds like that describes the prebate.
The FairTax bill describes the prebate as:
“Each qualified family shall be eligible to receive a sales tax rebate each month.” A tax rebate is typically referred to as a reduction in taxation demanded. The prebate is a tax refund as it says in the bill.
An entitlement is something created by a law that must be funded by congressional apportionment action - typically each congressional term.
If your kids live in your home as a family unit, they don’t get a prebate ... you do, considering them as additional kids in your family.
