It's hard to tell. Maybe a lot will stay and we'll have a lot more chinese expats laying around and effectively claiming territory like what has already happened with Vancouver. Maybe they'll be drawn back to China in one form or another and they'll use it to boost production/planning for tertiary and quaternary industries, so China can rip off less and create more (although that seems like antithesis to general chinese culture and attitude). Perhaps we'll see more focus on rich chinese in university and the average student will be shafted even further by rising prices and student loans. In any case, I can't see a scenario being good for the average graduating millennial, with foreigners moving on to take high-education jobs as well as low-education and trade work, whilst those born here must suffer and overstuffed market and waves of incoming debt.
