PRC still huge market for many multinationals, access is there for those who play ball. If anything PRC willing to reserve market share for foreign companies to maintain relations, i.e. no reason Nokia/Ericsson should have 5g contracts in PRC but they do.

As for PRC talent, no bamboo ceiling and increasing mccarthyism targetting PRC individuals big perk. Most people are happy being mere millionaires than billionaires. And even billionaires fine if you don't go full retard like Ma and try to challenge state regulators. Best of PRC minds are staying in PRC, this isn't the 80s-00s when PRC was sending their best as state initiave to be educated abroad, most of the students going to west now are those with some English proficieny but can't hack it in gaokao. There's a reason why more and more sea turtles are returning to PRC for better prospects. Or why US has to literally sanction Chinese Americans from working in PRC semi.

Plus PRC high skill demographic divident, the kind that drives innovation + high tech, high value development is just starting. The greatest pool of high end talent in human history is being churned out as we speak despite broader demographic decline that only makes PRC more resource independant. PRC won't peak for another 20 years, by then they will likely have sufficiently caught up in most advanced sectors to start eating the west's lunch. The convergence will be PRC closing gap which will erode western dominance by denying PRC market and wrestling shares from emerging economies fine with cheap PRC exports at the expense of west.
