So for the same $600, after forwarding on the NRST, you end up with about the same amount of money if not more at the end of the day.Minus another 23%.
After the Fairtax SBG would collect $780 to net $600 then pay 23% of that when s/he spends it.
The total percentage of his/her gross income to the Fairtax would be about 41%.
If his/her service was worth 30% more, don't you think s/he would be charging that now?
(I’m a he.)
