Any capitalist nation must embrace the process of "creative destruction". Progress is made by allowing the new to replace the old. If people lose their jobs at MySpace, then it's not a problem because people are being hired at Facebook. People who use social-networking sites now have an (apparently) better service and nobody is calling for the government to save MySpace.
If an auto plant moves from Michigan to North Carolina, the new workers might be paid less, but Americans are still being employed. A laid-off worker in Detroit could move south and get re-hired.
Now, what if the auto plant moves to Guadalajara? Is it the same thing? Clearly not. Even if an American worker were allowed to take a job in a Mexico, he would have to declare bankruptcy. What American could pay his bills on a $2 per hour wage? He wouldn't be able to pay his mortgage, credit cards, or car loan. On a large-enough scale, that could cause a banking crisis. He would also be paying his taxes to the government in Mexico City, rather than Washington.
Since the era of wide-open, free-trade with low-wage nations kicked into high gear a decade ago, the USA has seen an explosion of people on food stamps, a banking crisis, and a government budget crisis.
All of these crises are caused, to a large extent, by the "Creative-Destruction Deficit", to coin a phrase. If all of the destruction-part of capitalism is taking place within the USA, and the creation-part is taking place in Mexico, China, and India, then we shouldn't be surprised when the USA starts to look more-and-more destroyed.
