If we ever get iPhone manufacturing in the US, it's going to be massively automated factories, overseen by a comparative handful of employees. Because the US population just wouldn't be there for putting up an entire Apple factory city with hundreds of thousands of workers densely packed in, doing hand assembly work all in one location. Apple would have to import workers to do that kind of work in the US.Do i still think we should build SOME items here in the US? Yes. Do i ever imagine a situation were we build iphones here? No!
