What are the reasons why many immigrants from China in the United States can't really integrate into American upper class? Isn't it true that efforts may not succeed in America?

1. There are many reasons, so it is impossible to explain them all at once. For example, most of the upper class in the United States is still dominated by whites, and there are not many people of color entering; Differences in culture and consciousness may be the main reasons. At present, the children of China immigrants have grown up in the United States, and they have improved compared with their parents ... I think it takes several generations of efforts, just like African-Americans. Their status today is a long-term effort, even at the expense of blood.

2, efforts may not be successful, this kind of thing exists everywhere; The definition of success itself is more difficult to judge objectively.
