But,the great difficulty with the so-called Fair Tax (the national sales tax you hope for) is that all purchases will go offshore to non-sales tax entities.

That is why the constitution established a means of capturing those taxes - it's called a TARIFF. Of course, our vaunted corporations will fight that tooth-and-nail!

"...it's called a TARIFF."

A tariff is laid upon goods which are imported by companies for resale or inclusion in further manufacturing. Buying from offshore simply involves UPS items coming from Mexico/Caribbean/Japan/China/etc. Can you imagine them opening each package? Can't be done. How about self-asigned value? Hmmm. $ 0.

There is no way to capture each sale as it enters the US. AZ tried to compel folks to fess up to all purchases made from out-of-state sources so they could assess a "use tax". Results? Everyone said $ 0.
