I can assure you, engineers are out there who want to work in the US - both local and foreign. They just don’t want to work in Arizona.
The climate in California is already bad enough, but at least Cali has some upsides.
You do know that AZ is one of the largest engineering states in the country right? Motorola, Stryker, Infosys,Cisco,Honeywell, Raytheon, general dynamics, on semiconductor. And more that I don’t want to type all have r&d and fab in or near PHX. This is all about TSMC coming in thinking they are hot shot and that their name is worth more that the paycheck.
You forgot the highest volume Intel fab in the world XD. But you’re right Arizona at least has nice weather almost half of the year and tons of hot jobs in tech. The issue is with the work culture at TSMC and not the location
Cali is for pumping consumers as much as possible az is making the most advanced systems the military can think of. It’s not a shortage of qualified engineers
Giving green cards for Arizona isn’t the issue, people will work where they’re paid. The point I’m making is that TSMC is going to have to offer green cards for this work in the first place.
