We need reasonable policies based upon factual analysis and prudence. I recognize the theoretical benefits of totally Free Trade whereing each nation and individual uses his/her comparative advantage in a free market to approach the optimal production and distribution of goods and services. The problem with the theory is that in practice it does not work according to the theoretical model. The founders of this nation were very much captialists and belived in as much free trade as possible but they also understood the benefits of protective tariffs and implemented them from the star of our Constitutional form of government.
The former is a cornerstone of capitalism. In order tp work, the latter depends on the former for everyone concerned. Therefore, "free trade" (as it is currently envisioned) between differing economic systems will never happen.
