..my argument is that, if a National sales tax is instituted, the employee will still expect the same gross salary

I agree. There is no reason for a change. If you agree to $50k per year, that's what you'll get. But under the nrst, your taxes will be paid when you spend, not be taken form you before you even put your hands on it!

That I agree with. But do we agree that gross prices will increase?
