What are the negative effects of high-end people emigrating to China?

There must be some negative effects, but everything has two sides.

First, the outflow of high-end people will cause the country to lose some talents, and second, the outflow of high-net-worth people will also cause the loss of some assets.

But there is nothing wrong with immigration itself. After all, it is a personal choice. Everyone has the right to pursue a better life, better development, better asset allocation and better education and medical resources.
