Explain every Japanese, German, South Korean, etc. auto plant built in the U.S. in the last twenty years or so in the absence of "anti-dumping" policies.
I've no confidence they're going to stay here much longer. Ford, GM and the rest of them are closing up for cheaper labor and so will the foreign automakers eventually. These Free Trade agreements with third world countries is relatively new policy starting with Poppy Bush, their effects are just now beginning to bite us big-time.
