Thousand talent tier incentive is drop in the bucket, most sea turtles return because only so high you can climb in US with cold war bamboo ceiling. Past certain point, both US PRC can cut big checks, PRC lets a yellow face climb to top.
South Asian (Indian) / White / East Asian ceo gap something like 3 / 2 / 0.5 per million pop in US. Chinese long recognized this ceiling, and more are returning to PRC because of it. More and more, PRC getting Chinese returnees that are credentialled 40yro stuck at manager / director level who see greener PRC grass leaving after accumulating industry knowledge / experience taking their entire network / ip / tacit knowledge with them. PRC use to pay a lot of recruit these folks, but we're at that point a lot of Chinese Americans from 80s-90s are in their 30s-40s, who know how high they can climb in US. Meanwhile PRC printing highend jobs that attract Chinese talent with comparable compensation, and a better title / social status.
CEO gap mostly goes away when controlling for pop. age / cultural differences (less assertive), not nebulous racism like first comment. PRC still pays a lot to recruit through 1000 talents, USDOJ continues to uncover cases where $X00,000+ offered for IP / research. Meanwhile Chinese (m|b)illionaires make exit plans in case they get Jack Ma’d or worse.
Yes, yes and Asian tertiary applicants has worse personality except not. Eitherway, I didn't bring up racism. I said Chinese want leadership positions, they're not getting it vs the usual other races in US, so some go where they can get it, which happens to be increasingly PRC.
X00,000 USD is... not a lot anymore. That's normal compensation for high tier jobs, aka PRC tier1 opportunities is simply default globally competitive especially when you factor in other allowances. Top tier 1000 talent tier inducements where PRC build you a lab, give 7 digit in guaranteed funding, aka exactly the kind of opportunities bamboo ceiling is cutting off in US is pretty rare, almost rounding error in overall flow of talent. NVM DoJ has prosecuted ~0/150 thousand talent cases for actual espionage, i.e. never uncovered anything but candidates double dipping on PRC and NIH/NSF grants.
I don't know what billionaires capita flighting fraction of their liquidity has to do with anything. Ultimately whats more damaging for geopolitical S&T competition, capital flight, or knowledge flight.
