I don't think the Fed's will ever let a car manufacturer (from another country) under cut an American car builder enough to put them out of business.
Just look at what they did for Harley Davidson.
30 years ago when I bought a brand new Gold Wing when they first came out, you couldn't buy a comparable Harley for anywhere near the $2,800 I paid for my Honda. H.D. finally lobbied congress enough to get them to pass a high enough tariffs on foreign motorcycles to create a level playing field.
GM,Ford, & Chrysler will continue to cut jobs right here in the good old U.S.of A. as long as they can have the very same work done for a fraction of the cost in other countries.
Alot of people have told me that I have no room to talk, since I own a couple of Hondas that I bought brand new. That's when I tell them, that at least they were built right here in Ohio, and 2000 "Ohio" Honda employees benefited by me doing so. Then I usually go over and look at their G.M. cars serial # and show them that their car was built either in Mexico or Canada.
It's a world market, but unfortunately, our piece of the pie seems to be getting smaller and smaller.
