For decades the export of manufacturing sector jobs has been incentivized by policy. That’s the primary cause of the decline of the middle class, and that needs to change.
The technological change is nothing to fear, IMHO, What we’re seeing is the beginning of Industrial Revolution 2.0. These disruptive new technologies come with great opportunities. I actually think we are headed towards a renaissance of US-based manufacturing, but its going to look very different from manufacturing in the 1950s.
On the policy point I’m a pessimist, but I’m on optimist on the technological front.
