Actually the exact opposite is the truth. If one uses traiffs to give domestic producers a level playing field or even an advantage then the creation and distribution of wealth stay in the country which tends to make everyone richer. If have a great deal of experience in building weath creating domestic industries by protecting then from unfair foriegn competition with traiffs and such. It has worked well and could work well again. We have only 20 or so years experience at open borders, open market, "free trade uber allis" and we are getting our clocked cleaned and about to be over taken by the protectionist rising super powers of China and India.
One would be idiotic not to insist on at least a through and fair review of all these trade agreements that are sucking the life out of our domestic wealth producing industries.
Free trade is not a new thing invented by American Capitalists. Europe practiced free trade over 120 years ago and it failed miserably. Any bets on history repeating itself?
