If these company's don't want to move out of China on their own they can be forced out. We don't need Chinese nationals in the US getting degrees in fields that are actually needed, while Americans students earn worthless degrees, and come away indoctrinated and in debt. Our decline is from bad policy. It can be stopped, and reversed, by changing that policy. The Chinese economy isn't as strong as some think, and they will have a hard time controlling their huge population when things go south.
