The jobs are already gone.
Crony capitalists running the show on this side of the Pacific, and Chicoms systematically attacking our industries (predatory pricing, industrial subsidies, capital subsidies, slave labor) from their side. The American worker is caught in the middle, and the invisible hand is lost at sea.
Why have cheap imports compete with American companies, the founders reasoned. After all, they understood that we had the natural resources, the technology, the labor force and one of the largest consumer markets. Those basic conditions are essentially unchanged today.
I rest my case... :)
