The advocates of Free Trade deals between countries frequently cite the fact that more products are made available at a lower cost to consumers as proof that their idea makes economic sense. Their explanation of how this works rests on the idea of
Comparative Advantage,
[1] the idea that one country can produce a good at a lower opportunity cost than other countries. Based on this idea, if the industries in one country focus on those products where they have the lowest opportunity cost, and import products where they don't, this provides an abundance of lower priced goods for everyone. For the advocates of Free Trade,
price [2] appears to be the ultimate test of what is economically good. They scoff at opponents and critics of Free Trade as if their criticisms of it are completely without merit. Even
some economists who have dared to question Free Trade, still try to uphold Comparative Advantage as a reasonable idea.
[3] The reality is that the Free Trade ideology ultimately rests on Comparative Advantage. Therefore, it is prudent to examine the criticisms of it to see if they do, in fact, merit consideration. I believe that history has proven that they do.
