Do you think the world can sustain the lifestyle of the average American if the whole of Africa and China have it too? We need to change, and frankly those with privileges need to. Otherwise they would rightly claim that it is unfair.
Americans will mostly be jobless and replaced by automation, many goods will be exported and China will likely fair a lot better because it's already a place where "social credit" and other policies already exist which are more acceptable than what the USA will tolerate. Americans hate the idea of free healthcare and UBI for example.
I know the US media likes to pretend China is finished, but I really don't think that's the case, it will continue to grow, even if only by inertia.
