Yes, China absolutely did achieve all that by regulating their direction. It's different from of regulation than what US does, it's political regulation not so much economical one. There are way many constrains and regulations over there, people go to jail over there just like that if they don't follow up. There is no such thing if one company wants to show up on the hearing or not, no such nonsense in China. Take for an example that Alibaba guy, he was cocky wanted to be Musk like superstar and got shot down real fast. China right now is like America after WWII very firm and ruled by hand, that's why they are prospering so much. They invest into their infrastructure while US does not. US can't invest in people because it's biggest tax payers are not paying taxes and they don't have the firm hand to change the laws. US is as deregulated as it can be and asking for even more is trouble.
When it comes to manufacturing iPhones in US I don't believe one bit into a story that phone would be more expensive cause they can't pass that to a consumer. Apple would make less money, that's the trick. US manufacturing has huge issues, it has issues with nuts and bolts that's how bad it is. But, Apple sells 200 million devices a year so there is no way in hell someone cannot setup an automated factory and close down suppliers chain within reasonable time
