The Micron plant is a perfect example of political BS. I was in a position where my business provides a vital component to chip fabrication facilities, so I do know something about them. They're very highly automated and will require very few people to run once constructed.
The only real bump in employment will be to build them. But even then, some of this construction will be from outside sources familiar with chip fabrication facilities. Which presently, are mostly located in Pacific Rim and a lot of the equipment inside of them will be from Japan. Labor isn't a huge component of cost for chip manufacturing.
But I'm sure these facts are way above our Governor's head, and these would be ignored anyway since we want to spin a positive narrative.
