A fantastic read on the state of electronics manufacturing in the United States, and why the iPhone simply cannot be produced at the scale that China can:
Another critical advantage for Apple was that China provided engineers at a scale the United States could not match. Apple’s executives had estimated that about 8,700 industrial engineers were needed to oversee and guide the 200,000 assembly-line workers eventually involved in manufacturing iPhones. The company’s analysts had forecast it would take as long as nine months to find that many qualified engineers in the United States.
In China, it took 15 days.
