Technology, not “third world wages”, killed most of what manufacturing that has been lost in the U.S. and THAT has occurred globally, not just in the U.S. But time, and the inevitable rise of even more technology, can increase manufacturing here, IF - and its a big IF - we have a workforce that can handle it, not tariffs against IMPORTS, which many domestic producers (not just consumers) need.
Right now American job demand is running with almost 30% of job openings remaining open more than sixty days. That exceeds the deficits in filling jobs in most our major trade competitors. No wonder we export less. We have more of a critical blue collar skills and willingness to work deficit than we do an import surplus. We have millions of working age men and women either getting disability or unemployment or jut sitting on the sidelines, than nearly any time in history. Are they willing and capable of taking all these new jobs so many companies are recently saying they are going to create? Who can answer that?

I can't drive around town waving 3 dollars at every food market and demand they sell me a pound of ground beef. When nobody sells me any I can't then claim their is no ground beef available. What there is is no ground beef available for $3.00 a pound. If I offered $5.00/lb then I would get all the ground beef I wanted.
Automation has nothing to do with job loses due to offshoring. That meme is total BS. The two things are totally different.
