“Question: How does this [FAIRtax] affect U.S. competitiveness in foreign trade?
“Answer:
“Since all U.S. exporters immediately see an average 20-percent reduction in their production costs, they experience an immediate boost in their competitiveness overseas. American companies doing business internationally are able to sell their goods at lower prices but similar margins, and this brings jobs to America.
“In addition, U.S. companies with investments or plants abroad will bring home overseas profits without the penalty of paying income taxes, thus resulting in more U.S. capital investment.
“And at last, imports and domestic production are on a level playing field. Exported goods are not subject to the FairTax, since they are not consumed in the U.S.; but imported goods sold in the U.S. are subject to the Fair Tax because these products are consumed domestically.”
I like FAIRtax, and a border adjustment would be very similar.
