That's the point.
Free trade promised that high tech jobs would replace all those factory jobs. In the age of NAFTA they believed that all those displaced factory workers could just go to community college and study Visual Basic and become web programmers. Well, now there is outsourcing and those high tech jobs are being shipped overseas.
Half your labor force is composed of people of average or sub average intelligence. Not everyone is college material. In the Golden Age such people could just get jobs at the factory and be stable, productive citizens for life. They could buy a house, go away on vacation, have health insurance, and retire on a pension. Now, they do crystal meth as they drift from McJob to McJob. One of these days, the Democrats are going to stress restoring the old days of the job at the factory over sodomite marriage. And when they do, get ready for New Deal II.
Oh I agree with you on that point totally. Free trade was supposed to mean trading goods between countries. Instead the only thing America is exporting are its jobs - and important ones in technology and defense. Its like America is selling scrap metal to Japan in the 1930's.
