Apple is now the wealthiest American Corporation, but the jobs it created in manufacturing are in Asia. It did create American jobs in sales, service and applications.

As robots take over manufacture and warehousing, and the remaining semi-skilled jobs go to the cheapest source of labor, more and more people with limited skills- the "blue collar"- will be unemployable or working at the lowest level in sales, clean-up and the like.

Simply put, they do not have the education to take on, or even to be trained in, the technical, adjustable, workforce needed in the future.
I don't have any answers, but I know preparing people for the future requires changes in schools, government support programs, and single-group cultures .
