Global Competition
We live in a global economy. It only makes sense to produce goods and services that we have a competitive advantage or are competitively equal. If our goods are too expensive or the quality is poor, then customers won't buy them (either here or abroad). Now, you can bring non-economic decision criteria into the equation, but that will only go so far.
Concerning global competition, I think many Americans have a rude awakening coming. The competition from China, India, Brazil, Russia, the EEC (Europe), and the Middle East is real and is growing. Putting up artificial trade barriers will not work for very long. What we need to do is make sure that we are preparing our country (infrastructure, low cost & environmentally sensible energy policy, lower corporate tax rates, etc.) and future generations (education, etc.) for this global economy. Isolationism won't work.
