Yeah, about that, don't you think US first need to convince Chinese American engineers not to move to China first?They don't need education. They will just pay Chinese existing engineers working in rare earth companies 500K-1 million dollar salaries and those engineers will happily move to US or other countries. Their biggest advantage is extreme wealth.
They also don't need to worry about being efficient about their rare earth production either. They will just pay 10-20 times the current cost if needed to achieve non-chinese production.
I don't know where you live but there are not many people in the world who would "happily move to"
Are you sure US will still have "extreme wealth" if that wealth can't buy anything, things like RE?
But yes they can very much pay 10-20 times the current cost to achieve non-Chinese production, might be a bit difficult selling cars that cost 10x or going to war with China with 1/10th (in practice much less) production.
