Right. It is extraordinarily difficult to just pack up a high-tech factory and move it to another country. Actually moving the plant and machines is the easiest part, the hard part is the people. Training people to be experts at high tech jobs takes a lot of time, and even then you're losing the decades of experience and the high concentration of likewise experienced and well-trained suppliers nearby. Of course we could just move the people here too, but our current immigration policy doesn't seem too fond of that approach either.
