Both of you couldn't be more wrong.
As someone who lives in Upstate NY, where GlobalFoundries recently built a similarly priced $7 billion fab (and growing) that is used to make processors, I can assure you that fabs of this scale create and maintain thousands of jobs.
It's a huge boost and capital injection into the local economy.
Of that 10,000, half of that is easily administrative and 'in-house' employees. The other half are local labor unions, speciality maintenance contracts, etc. It takes a lot of work to run a fab.
I recall NYS being in the running for this factory in that area until a corruption scandal derailed it. Whether it is long-term or short-term, there will be more jobs involved than existed before. Not to mention the spur to the local economy.
