But this still isn't the whole story. The Chinese-American population is bigger and more diverse than the Indian-American or Pakistani-American one. There are lots of families in all these groups where the generation that immigrated to the US was well-educated and professional. Even if that generation had to work extremely hard to get a foothold in the new country, the children benefited both from the high education level of the parents, and from the hard-working/aspirational mentality of the recent immigrant, and (she argues) from the traditionalist approaches to discipline and education which the parents brought with them.

These are the people whom Amy Chua is talking to and about.

The average Chinese-American income reflects relatively fewer of these highly successful immigrants, because there are many more Chinese-Americans who arrived in the US poor and with few options. That doesn't disprove what she said.
