Maybe this will help. What if every single car the Big Three made, as fast as they could make them, were sold overseas? Every stinking one- they were all exported. Would that make you happy? Full employment in the US auto industry. The Big Three are all smiles. The parts suppliers are all smiles. No "Buy American" involved here. Do you think for a moment any of the Big Three would quit making cars because they weren't being purchased by "Americans"? They could care less! If they don't care who buys their cars, why the heck should you? As long as SOMEONE buys them. Overseas buyers are thrilled. Think about this. Do you think German car makers are encouraging Germans to buy German? I doubt it. They are doing quite well selling German cars to Americans, thank you.
Now, say you are in Japan. Same situation-all Japanese cars are sold in the US. Japanese auto makers are happy. Their parts suppliers are happy. Americans are happy to buy their cars. Dealers are happy to sell them. Mechanics are employed keeping them running. Everyones happy.
Buy American? Buy foreign? Nobody cares. Everyone is prospering. Don't buy foreign? Don't buy American. Everyone loses. That's what is happening today- a global downturn in demand- nobody is buying, and everyone is losing. And, FYI, it is much worse in China and Japan than here. Chrysler and GM were much less well-positioned financially to handle this downturn than there foreign counterparts.
What I am saying is that economic principles are not about to bow their knee to some misplaced sense of economic nationalism. If American products are competitive, Americans, and everyone else, will purchase them. If they are not, they won't.
Case in point. In the February 21 edition of The Economist magazine, there is a table showing the percentage of domestic auto parts suppliers also selling to Asian and European car companies. As an example, 65% of parts suppliers selling parts to Ford also sell to Asian car companies. Nearly half of the Ford suppliers also sell to European companies. Unless you are an economic idiot, you should be happy those suppliers are selling to foreign companies. But if we don't buy Toyotas, Audis, as well as Fords, those guys feel it.
I encourage everyone to read a book called The Undercover Economist by Tim Harford. It is a layman's language book on economics. It explains how grain from Iowa, pumps from Ingersoll-Rand, and jetliners from Boeing cross the ocean and return as Toyotas and cell phones. And we all win from it.
