The US graduates vastly fewer electrical engineers than any other comparably large nation. We are about equal to Iran. The idea of moving semi manufacturing here is about as likely as it going to Iran. I am sure you just assumed that the US is the best at everything (or even most things) and this is a shock to you but please look it up. It is a fact that the US is a third tier nation at best in engineering and it has been that way since the 80s
