"That would be the result. We can tax imports and get the same result without an NRST.
Either way the consumer loses, but you get your result."
Except by only adding a tarrif, you are talking about additional taxes vs. the NRST which is revenue nuetral. Under the current system the taxes are hidden, under the NRST the taxes are in plain view and the base is larger.
Remove government taxes. Remove regulations. Institute tort reform. Encourage non-union shops.
Do it right.
