It's been happening. Part of my job is assembling statistics on the matter. Manufacturing jobs are vanishing from this country, just as farm labor is. Either you automate, or you outsource, but either way, you lose manufacturing jobs. THAT has been going on since the late 70's. Services is the mainstay of our economy, and it's staying that way.
But politicians like to visit towns which have lost manufacturing jobs and like to wax poetically about bygone eras and how Washington has let all their jobs float away in a morass of corporate greed. Yeah. Right. Maybe some of it is true, but it's like bemoaning the loss of the horse and buggy. It's NOT coming back, and placing blame for the loss of the horse and buggy should not result in incentives to bring it back.
Third world nations are nations with basically an agricultural or raw material base. Second world or "developing" nations are ones based on industry. First world nations are nations of service and information. And that's life. I just hate hearing about how these jobs are lost, but the reality is, they aren't ever coming back, nor should they.
If you only know how to program on PDP-11's or the Univac and only know COBOL, do us a favor and retire - or learn something new. That is how labor should be moving in this country. The old way is gone. It will not be back. Let THEM do that work.
