I don’t get the point. A sales tax is in addition to the price on the sticker.
Ok.
The milk costs you more than the milk did before.
Ok.
However, you don’t have to pay (additional) income taxes.
Therefore, assuming for the sake of the argument it’s revenue neutral for the individual, the cost, is the same.
If that was their argument, I would let it go. But their argument is that everyone will have more money and prices will stay the same. The reality is, if it is revenue neutral, there will be winners and losers but overall people will be about the same. But reading the fairtax propaganda, it is the ultimate fairytale. Everyone wins big.
