This is a good question.
As a bastion of liberalism, the America is certainly the place that the capitalists like the most, where they can get the most control.
Several top Chinese rich people have publicly expressed their desire for power and American style system more than once. Ma Yun tried to establish his own elite group club in the name of "founding a university", but was ordered to terminate.
Some people say that these rich people have taken advantage of the trend of the times and seized the opportunities, but they mistakenly believe that they have gained all these things only by their own ability. In order to develop the economy, the government acquiesced in many of their illegal and criminal acts to a large extent. If they use the business strategy they often use in China in the United States, they will only get various claims and penalties and become bankrupt.(Explain: This means that the profit making methods of these Chinese capitalists are very inferior to those of American capital groups,they lack technology or are mere vassals of western capital groups)
It is normal for them to want to leave. They know how dirty their money is; It is foolish for them to want to leave. The ruthless plundering of Russian capitalists by the West during the Ukrainian war has proved everything.
They would just need acceptance by the American elite. In theory this would be hard due to American nationalism, but in practice we have often seen that for US oligarchs, money and shared "interests" run much thicker than blood.
The American government is far far more accomandating of illegal acts, but in order to enter American high society, the approval of the oligarchs must first be gained. And seeing cases such as Guo Wengui, it is not too difficult as long as one has the same twisted and corrupt mindset.
Ultimately China creates so many rich people that it runs by far a net positive. And when you're holding the world's largest economy, leakages through corruption is inevitable, and these corrupt people that are the enemy of the country will seek the like minded, unless they are arrested or concessions are made to accept them.
Since arresting them all is impossible and making concessions to them is unacceptable, there will be continued outflow of dregs that have something to hide to overseas oligarchies that protect such types.
