The so-called “decoupling” of the US and Chinese economies is NOT happening. Their economies are too deeply intertwined. The reality hidden by “decoupling” is just capitalism’s usual uneven development. Capitalism relocated investment away from its old centers (Western Europe, North America, and Japan) to China, India, Brazil, et al. The US cannot stop or reverse that process any more than Britain could stop or reverse it in the 18th and 19th centuries. Wars fail or worse. The only real option is mutual accommodation.
