The problem is the USA is a consumer economy which isn’t sustainable. We could get away with it as a tech leader, but with China stepping ahead (Deepseek) china will be a tech leader and manufacturing leader. What will the USA have?
China is what now? China is the biggest trading partner of something like 70% of all nations in the world!
China is asymmetric and unfair, not "isolated". They disallow imports except in a handful of industries they can't replicate yet. That works for China, because: (1) they are huge, and (2) they remain poor, and thus can do the low wage jobs internally in addition to doing them for the rest of the world.
The US only has advantage #1. Though at this point #2 seems within reach...
