If manufacturing in the USA is so difficult, why do German, Japanese and Korean cars get built here? And the QC of cars today is light years ahead of what it was 50 years ago. Short term profit maximization isn't necessarily a good business decision.
My understanding (and I'm sure someone will correct me) is that small electronics (think iPhones) aren't made here because they need to keep the factory going 24/7, and they can't get reliable maintenance people.
