Wouldn't it be great to pay no Federal Taxes as long as you buy no Foreign goods if the Federal Government got all it's money for operating expenses from import Tariffs as spelled out in the Constitution?
I oppose a National Sales Tax because it would be just as Un-Constitutional as the National Income Tax is now.
Actually, it would be a uniform excise tax as allowed by Article I, Section 8, Clause 1 of the U.S. Constiution:
The Congress shall have Power To lay and collect Taxes, Duties, Imposts and Excises, to pay the Debts and provide for the common Defence and general Welfare of the United States; but all Duties, Imposts and Excises shall be uniform throughout the United States;
