Remember reading about an old interview article with Tim Cook.
"The products we do require really advanced tooling, and the precision that you have to have, the tooling and working with the materials that we do are state of the art. And the tooling skill is very deep here.
In the U.S., you could have a meeting of tooling engineers and I'm not sure we could fill the room. In China, you could fill multiple football fields."
Labor is one factor why manufacturing won't return to the U.S. as America has higher standards and costs of living. Automation is used a lot in manufacturing so maybe not as much manual labor is needed? It depends.
Another are lots of regulations in America... local, state and federal.. safety, work, environmental, etc...
Buying land is costly to build a factory and then consider the infrastructure needed to support that factory and the workers.
Anything made from a U.S. manufacturer most likely means higher costs to produce which is then passed onto consumers. People already complain about $1K iPhones so imagine if it goes to $2K?
What about Mac computers like a MB Pro? If anyone thinks $2K is pricey, what if it's priced >$3K as the starting point?
Any cost increases will be passed onto consumers at higher prices.
Apple is a corporation & its primary concern is profits for itself and its shareholders.
The Jobs era is gone as Cook is currently in charge. Need to move on.
