Unemployment rates are like 4%, population density is like 115 people per square mile, and workforce participation is like 60%.
That's like ~2.8 per square mile you can employ. That's not even ~100,000 people in a 100 mile radius. No way you're going to attract 10% of them to work in your factory.
Somewhere like Detroit might be possible - ~4.5M people, 6.1% unemployment, ~62% participation = ~170k - a lot with previous manufacturing experience.
All that in a ~33 mile radius instead of ~100 mile radius...
I think that _something_ like this will eventually happen, as SEA moves up the wealth ladder.
Considering people will by an iPhone almost no matter the price... why not manufacture some in the US, with minimum wage jobs and no worker exploitation, and charge $1500 a pop for 'made in the USA'?
Imagine iPhone factories in West Virginia, Romania, and India, to start. I suppose the economics depend on how much you can spread out component manufacturing: I know TSMC is the only manufacturer even capable of making the top-of-the-line iPhone SoCs at this point, but I suspect batteries, motherboards, cameras, metal, and glass have a little more competition.
