From an economic model standpoint, economies evolve. Basically they start out as farming and selling basic goods, then move into a manufacturing phase, then move primarily toward a service based economy.
1. How do we bring manuf to the us? Either decrease post secondary education, set a price ceiling for some reason on manufacturing outputs, or create some huge exogenous demand.
2. See 1. No we do not want to bring more to the US. It does not lead to full employment of our workforce. Not employment in the typical sence. I'm talking underemployment, I.e. a law grad working as a cnc operator. He is technically "employed" but not fully because his earning potential is much higher. Basically our workforce in the us, at a snapshot, is highly educated, and trained for service based positions.
