Another thought, what city has 30-50,000 people available to work in this huge factory. Does any city in America have that many out of work at this time? This isn't 2008 when cities like Vegas literally had over 100,000 unemployment.
(Please don't quote me on the number), just for reference.
Oh yes, they said they would like to build in the middle of Pennsylvania. No way in gods green earth will they find 30 thousand much less than 50 thousand in the middle of that state.
You're right that they won't find 30-50K there. But the eastern half of PA is actually a very good place for industry. If the plant is highly automated - as it will have to be - then the numbers are manageable. And that area is full of light industry that's not dissimilar.
My mental model may be wrong but it's this:-
- a low automation factory with 500 - 100K lower-paid workers
- a highly-automated factory with ~ 5K higher-paid workers
The deciding factor may well be the "local supply chain" which is exceptionally good in China (because China concentrated on it, unlike the US). Without the supply chain, the other issue are moot.
As an example of the supply chain effect, consider the auto industry in the southern part of the US. The late 70's were a dark period for the US automakers. Several Japanese manufacturers realized that they needed to have US plants and the first to jump was Nissan, with a small-truck plant. Many states tried hard but Nissan eventually decided on a small town south-east of Nashville, TN. It was a HUGE success. A Ford glass plant in Nashville that had recently shut down, immediately reopened. And within a few years, all the parts suppliers (brakes, glass, shocks, electrical, etc etc) were located within a 100-mile radius.
THAT is what China has with iPhone production. And it is exactly that type of supply chain that will be needed for any serious attempt to make iPhones in the US. As all farmers and gardeners know - seed is not sufficient to produce a harvest, the ground must also be fertile.
