EDIT: Article says 1,600 for the fab when its at full capacity and "thousands indirectly", which of course means restaurants and services nearby.
Looks like its going to be built north of Peoria, which puts it near Glendale, Phoenix, Tempe, Scottsdale, etc. This'll probably add jobs worth about $100,000,000 - $150,000,000 a year. Somewhere in that neighborhood. The support-based jobs probably $150,000,000 to $200,000,000. Adds another $8.5 to $28 million a year in tax revenues for the state and cities.
Electricity, infrastructure, Additional cost in Tax, Environment protection etc. All of these add up very quickly.
It is not impossible. But it doesn't seems Government cares that much other than talking about it. There is also the close proximity with other supply chain. Where there are currently close to Zero in US.
Also, not sure how the jobs will break down, but when I was at Intel, techs actually working in the clean rooms were not making anywhere near 6 figures. They commonly told me, they were just there for the stock.
