Complete non sense!!! The whole point with bringing manufacturing back to the USA is to allow for the range of jobs any community needs. The idea that factory work is low skilled is complete baloney, especially in any modern automated factory. By bringing back manufacturing we open up a board spectrum of jobs from the level of a floor sweeper up to plant manager. In between you have technicians, programmers, engineers, metrology people, nurses, QC organizations, compliancy managers (safety and the like) and whatever a specific plant requires. Your use of the phrase "low skilled factory work" highlights a complete ignorance of what is required to run a factory. Often we see an upside down pyramid (somewhat) with the number of production workers athlete bottom.
AS for what happens in TEN years hell we could all be living in the stone age again when nuclear war destroys all of our electronics. You can't be assured of working on one plant forever. If nothing else technology moves on or you could suffer like many manufactures when a company like Apple wipes out your business.
