Chinese Workers Abandon Silicon Valley for Riches Back Home

It is understandable why somebody would want to return to their home-country. The "Bamboo Ceiling" the article discusses is incredibly concerning. It's America's loss for sure.

I'm curious (1) how much of these people's education or experience was subsidized by the American economy and (2) how common the same situation is in China (i.e. US expats training up in China and taking that expertise back to the US).

If (1) and (2) aren't aligned, it could be one of the factors contributing to the growing sense that we pour a bunch of money into higher-ed without seeing much return.

I don't mean this from a US nationalist or political perspective - I'm merely speculating on the economics. Are the incentives for coming to the country aligned for both the person and the country? Many companies will pay for employees to go to grad-school but demand repayment if the employee isn't still with the company N years later. Would such a system for college/work visas make any sense to help keep talent?

This is a very valid point and you must not be afraid to be seen as a ‘nationalist’ (whatever that means anyway).

One of my biggest concerns with China - as a a European - is that Brussel allows Chinese companies to buy huge amounts of European IP(eg robots, automotives, AI) but the Chinese government, on the other hand, forbids (or makes it very difficult) that foreign companies buy Chinese IP. So its a one way road !

Luckily some government officials now realized that and are actively trying to combat Chinese acquisitions (eg German foreign minister), but its still a real danger. China essentially takes huge advantage of our openness and our liberal markets but does not return the favour...

Where did you find that Chinese government forbids foreign companies to buy Chinese IP? Market is fair, someone wants to sell, someone has the money to buy, this is how business is done.
