Manufacturing, regardless of where it is happening on the globe, is now chiefly done by robots.
I’d expect no more than a minor bump in employment numbers regardless.
On that point, you’re mistaken. It does not apply across the board. There are industries with a fair amount of hand work, and there are industries in which the latest, greatest machinery cannot be cost justified. Textiles and furniture are among those. This is a low wage area, non-union. Maybe your thinking applies to New York or California, but not the south outside large urban areas.
