Wrong. That is how every state that has a sales tax defines it. The fairtax tax s0-called 23% sales tax rate only exists in the vocabulary of the Fairtax. No one else on the planet quotes rates in inclusive terms.
"Wrong."
Don't be silly; even some entertainment/resort businesses quote their prices as tax inclusive. The fact that most retailers presently use tax exclusive calculation is merely a historical accident since that's how the existing state sales taxes originated, nothing more.
And as has been shown the same amount can easily be calculated by using the tax inclusive rate - which rate is the one used throughout the FairTax bill. Attempting to change the rate into something that sounds much higher will accomplish little since most other people will realize that the amount of money is the same no matter how it's discussed. Since the bill uses tax inclusive throughout and since the required receipt specifies that and since income tax rates (which the FairTax must be compared to) are also tax inclusive, the use of tax inclusive is eminently rational.
Check, say, Disney's website to see them specify tax inclusive ticket pricing.
