You may be right about that.
My experience with VAT, such as it is, was in Europe.
Anyway, I think we agree that the 999 plan does away with embedded taxes in the price of goods?
The difference is in the incentives that a sales tax provides for people to cheat, and the additional paperwork required to keep track of VAT taxes paid.
But, all other things equal, a sales tax and a VAT tax, at the same rate, would produce the same tax revenue and the same gross margins.
I agree about the hidden taxes being removed.
And I like the incentive that a sales tax provides consumers to save money (for investment or retirement) instead of spending it.
