Two of my daughters were part of a sister cities exchange and I can say with authority that the Chinese students that came to America did not behave like the other student nationalities. The Chinese students were not behaving badly or rudely, they were just very quiet and passive as if they had never had much free time while growing up for social interaction with their peers.
Chinese parents rate their duty to prepare their children for financial success much more highly than we do.
Different, not necessarily better or worse, ethos.
Go to any where smart people congregate like medicine, science and even law and you will find Jews and East Asians very well represented. In fact, over represented.
Let’s hear it for Hernstien and Murray’s Bell Curve. The book tells us who the smart people are.
