Ok, so it sounds like there's enough manpower to support... 300 some-odd new sites! This is the reality of what happens when jobs become obsolete. Sure, if all you know if manufacturing, you personally may be in a bit of a pickle. But the world was full of people that knew nothing but taking care of livestock, or riding horses, or hunting bison, or reaping wheat, and their children's children do other things now.
Besides this mundane quibble, what would the alternative be? Stop making new stuff? Purposely promote advanced technology that doesn't make anything easier for people? The back-face of this "woe is me, my simple job is gone now" mentality is, "finally, no one has to do that boring shit anymore!"
