I have had the pleasure of witnessing several manufacturing job’s return to the US. Using new robotics, i have seen several young entrepreneurs start to supply custom , performance enhanced car parts from their 3D robotic printers. Those jobs are coming back, but not to factories like they used to be in. Most of them i have seen are small businesses using cutting edge technology.
Using those 30 foot wide stalls in business parks?
When I lived in Seattle I worked with a few parts vendors for Boeing. Some of them worked out of their garages or those business park spaces. A lot of manufacturing goes on like that - to this day.
The only problem is that every single employee needed will come from the right side of the Bell Curve.
