>6/7ths of the world to pull from. Realistically US draws from ~1.2B of English speakers. PRC draws from ~1.1B of Mandarin speakers. Actually pool of relevant STEM talent is obviously much smaller, but PRC generates about as much as all OECD countries combined, which is multiple times US can absorb via immigration unless (unpopular) shift in policy. PRC academic / S&T / R&D pipeline is maturing towards generating "best and brightest" in numbers comparable to rest 6/7th of the world, much of whom are already retained in PRC. And despite how many Chinese foreign students are in western universities, this isn't the 90s anymore where CCP actually sent out their best and brightest to learn abroad, most of the international PRC students now are those who can't hack it in high competitive PRC system but have the wealth to pursue education abroad. They're extremely competitive bench warmers. Which isn't to say US brain drain isn't a great competitive advantage, it just may not be disproportionately so, something that keeps US in the game instead of thoroughly dominating it.
