Bringing them back now is a good idea since the current administration is probably going to try to pump money into the US manufacturing industry. If Apple can get a piece of the pie (Tax breaks, grants, etc) from the government, they'll save the shareholders some money.

I don't believe this move will be of help to those who are unskilled in the middle of nowhereville, USA or in old manufacturing hubs, though. Many of them don't even want to be re-trained for a new industry because they are holding on to the old past time of working in a specific industry with the hope that it will be brought back. They want jobs, but they specifically want them to be in whatever industry they used to work. There are still people that believe that the car industry will return to Detroit soon. It's sad, really.

These jobs will probably only last in the short-term, anyway. The employees will, more than likely, manufacture the robots to build Apple products so that they can fire all of their human laborers in third-world countries. Then, they'll cut down on the jobs they've created in the US also.

If there is any doubt that automation is taking over more quickly than imagined, see
