So, instead of moving some of their money offshore, wealthy citizens (you know, the ones who actually contribute to the economy) now have the incentive to close up shop and move themselves and the entirety of their assets overseas.
Congratulations, that is exactly how you have an exodus of 1.2 million affluent citizens underway.
To be replaced by millions upon millions more in China. Those who move in this day and age are the who already made their bones with RE and old standbye exports like shoes and toys.
If you are in the high value space -- EVs, green tech, semicon, aircraft, HPCs, etc. -- there is no better place to expand and grow than China.
China gave up far more during Deng's era when he let the highly educated -- educated by the state too -- leave for secondary education in the West. In the beginning less than 10% returned. But we saw what happened afterwards.
The ones leaving would leave anyways by pushing money they earn in China out of the country as "investment" into Vancouver, Flushing, Monterrey Park, Markham ... this claws back at least some of it.
Over time, they'll learn that investing in the West other than property, like for actual business, will get them little beyond maybe a chain of McDonalds in Chinese neighborhoods or Panda Express franchises if they venture into white suburbs. At which point, like the Overseas students they'll start re-investing in China.
