I think you misunderstand my position, and the reality of these misnamed (to fool You) freetrade agreements. I favor free trade, to use your example, do California, and Alabama have a free trade agreement? Then why do countrys need multithousand page agreements to trade freely with each other?
These free trade agreements are not about free trade, they are designed to put the U.S. at as big a disadvantage as possible. There were many unintended consequences to NAFTA that are not being reported. Many of the Manufacturing plants built in Mexico near the border are standing empty, they have been moved to the Orient, where the labor is cheaper, and the restrictions are less. Because of high yeilds in the U.S. farmers here can grow corn, wheat, etc. much cheaper than the farmers in Mexico, many Mexican farmers have put out of business by the grain imports since NAFTA.
If these were actually about free trade they wouldn't consist of thousands of pages of restrictions, requirements, and one sided penaltys. If you don't believe me, enter NAFTA, or North American Free Trade Agreement in a search engine, and go read it.
