America underestimates the difficulty of bringing manufacturing back

No kidding!

Beyond the obvious skilled labor there’s supply chain network, maintenance, townships and supporting system around them.

And all of this needs human labor which is taken from somewhere else. How do you incentivize them? Just throwing money at the problem won’t solve it either. Because more often than not it’ll attract charlatans who will promise the sky, take the money and move away.

Americans have a very 1980s idea of manufacturing (and China in general) in that there aren't actually that many humans being used in Chinese factories let alone the American ones some of them want to build here. There's even a concept of, "Dark Factories" in China which are 100% automated factories that operate in the dark. The only jobs that will come from bringing manufacturing back to the states will be in automation, robotics, AI, and roles to support those things.
