> the country would become incredibly attractive for manufacturing exports

First, the US will not be attractive in any way for investment because it is run by a madman that has ridiculous tariff policies that make starting manufacturing supply chains nearly impossible.

Second, even if the US could transition its economy back to manufacturing, that's a massive slide down the value chain to far less profitable industries than our current tech, biotech, and service driven economies. The idea as presented is a serious downgrade in quality of life compared to today.

> If you think that China is going to shut down the majority of its factories, move them to other countries, and let their currency float freely (well, freer than it is today), you're delusional.

China wants to transition its economy up the value chain to the high tech industry that the US currently has. It has the educational system and the brain power, and the biggest impediment, brain drain to the US, has now been shut off.

If climbing the value chain, out of manufacturing, requires China to shut down factories or open up currency somehow, they are far more likely to do that than to abandon their ambition of economic growth.
