the exact same thing was said for japan when their economy boomed. Whether china falls to the same fate, or actually sustain and overtake the west, is yet to be determined. However, trump's policies aren't really helping (but in fact, is actually enabling them). By removing the US as a large consumer, the CCP could be forced to switch to internal consumption model instead, which both increases the standard of living of the people there, as well as decrease the reliance on exporting (so lower economic leverage).
Not to mention the west's economic policies are disparate between supposed allied countries - with friends like that, who needs enemies?
