What is it that you do not understand. We live in a world today where the economy is increasingly a global one. Jobs should no longer be viewed as foreign or domestic. Job creation is job creation. Job creation increases consumption which increases employment as is demonstrated by the Okun relation. Economically speaking countries today are acting more and more like giant unions. The outcome is the same as the Unions of the past. Eitherway protectionisim in any form costs everyone, you, me, foreigners, and posterity. It would be wise for us to ignore the siren song of misguided politicians who promise to "protect" your job or the american economy. This is political hogwash meant to entice votes, not fix the economic problems of the country. Bottom line protectionism costs everyone. Who is hurts at any given moment is unique to the moment you are examining. In the long run the outcome is the same. Protectionism means fewer total jobs, less techonological inovation, and a stagnating economy.
