Mostly service workers will be thrown out of work. The one size fits all will not work in particular in the food industry. The prebate is regressive to low end earners and they will be the hardest hit. Also, let's pretend like there is double digit growth - can you inflation? ( not that I believe it).
Do you honestly believe that a family with four teenage boys and a family with four teenage girls who live across the street from each other will be "Fair"ly treated with prebates? Oh and no way food goes down you FT'ers magic 23%. Not going to happen.
Yes. The families in your hypothetical example will be fairly treated. The boys will eat more food, the girls will consume more clothing, shoes and make-up.
Query: Does the income tax make any distinction between boys and girls in the dependency exemption? Why should the Fair Tax be tasked with something Title 26 does not do?
