Toad is right.
The problem is nobody cares about those jobs that are leaving. Not until it's their jobs, anyway.
Of course, I don't live in sunny Texas or California. I live right in the dead center of the rust belt, and I get to see the results of free trade every day in the form of vacant factories and decaying infastructure. My old man was a steelworker (US Steel) who was forced into early retirement.. Don't worry though, it'll catch up to you sun belt boys in due time, too. The entire USA is going to become a giant rust belt at the rate we're going.
And, typically, John Q. Public couldn't care less until it's his own job at stake. Add in the fact that both the Democrats and Republicans are bought by the corporations who profit (in the short term, which is all they think about) from this, and we have problems. Sooner or later, we either have to protect what we still have or settle for Wal-Mart wages.
However, I don't think this is the reason Ford/GM are failing so badly. If it was, they'd have shut down all of their NA plants years ago. They're simply building stupid ugly cars and their dealerships make the buying experience as annoying as possible. Instead of comming up with their own ideas, the US companies are often trying to copy their rivals. Why buy a crappy copy of a Toyota when you can just buy the real deal, often for less money and with a much more pleasant purchasing experience?
Not like Hondas are all that great. Ever single one I've ever driven was a flimsy, small, cheap-feeling sardine can. They simply last forever with no maintenence and are easier for women and city dwellers to drive. If the US companies got their collective heads out of their posteriors, they could easily regain their dominance.
American management is notoriously short-sighted. Many managers would happily take risks that would potentially bankrupt the company in 5 years' time if it meant bigger profits this week. In fact when I was in college, the business school was training the up-and-comming generation of management to do exactly that. No wonder that rivals who take a more long-term view are gradually pulling ahead.

EDIT:
"Quality is exactly the same."
This part, though, I disagree with. The quality of the junk being built in third-world countries is NOT the same. Korean steel sucked so badly compared to what we were making it's not even funny. The problem is nobody cares about quality anymore (except in advertising slogans), it's all about the bottom line.
