> I've also taken Chinese bullet trains across the country, something I sadly cannot say for America
But exercising centralized control while eliminating internal dissent through propaganda or ignoring it because dissenters are effectively disenfranchised, as much as it's a thing many people in the US would love to do, isn't one of the things we outsource to China (neither, viewing the same claim through a different lens, is physical Infrastructure in the US.) So, to the extent that that story reflects something they genuinely have absolute advantage in, it's not really relevant to the “why do we go to them for the things we go to them” for. Heck, a lot of the things we have gone to them for, like low-cost manufacturing of a variety of goods, are moving out from China to other places as they develop just as they moved out of more developed places to China, because with more development comes higher proficiency in areas that less developed states can't substitute for at all, so comparative advantage leads to them getting more of the things they can do, even if they aren't great at them on an absolute scale.
