You'd probably be surprised to learn that China has "lost" five times more manufacturing jobs than we have. Some people like to blame these losses on bogeymen like NAFTA. More knowledgeable people understand that automation and the resulting increases in productivity are responsible for those job losses.
We produce more today with less people which is why manufacturing wages continue to increase in the US.
It's pretty difficult to increase wages without increasing productivity.
I'll be you and your friends at EPI lament the fact that we don't have half our population working in agriculture any longer. No doubt the Luddites back then shared the same feelings you have today. Thankfully, most people are paying attention to the facts rather than your feelings.
