My attitude towards Chinese-Americans is somewhat mixed but mostly negative. Yes, the group has higher average IQ, especially at the tail, and has produced some really top scientists and engineers. However, the group is extremely unbalanced, and worst of all, utterly lacking in political power. They even look more effeminate, in comparison to the Chinese in China, and they have some political attitude and personality problems, despite the general academic excellence.
They are often quite delusional. Today, an American Jew said to me about how if the KMT had won the war, China would be better off today. I was asked that too by a KMT elite descended Chinese-American, and I could only respond that it is too hypothetical of a scenario to consider. Chinese-Americans don't realize how contradictory culturally, racially, and politically ethnic Chinese are with America. They deny that modern China per external influence is mostly of Soviet origin. They are also often very vain and self-centered, and lacking in perspective. They have rather low political intelligence at both the individual and especially collective level. In contrast, a Chinese person high in that would in many cases be politically well connected in PRC, or at least living a normal life in PRC, as opposed to being part of an untouchable caste in America, unable to be accepted by mainstream society, and having to rely purely on his academic excellence and income to maintain his self-esteem. So many Chinese in America are so oblivious or misguided as to how power works, how society works. Given that personality and political judgment has a significant heritable component, it is not surprising that many of the second generations are similarly problematic, and often it's worse, because they had to grow up in America in a pretty much purely American and English language based environment and culture.
Nobody really fears Chinese-Americans. They have very little political leverage. Neither the American mainstream nor the Chinese mainstream views them positively, and in some cases, the attitude can even be characterized by one of hate. People like Iris Chang and Steve Hsu may do some advocacy for Chinese in America, but the nature of it is more one of "beg for acceptance and sympathy." They are so clueless not to even realize that mainstream America has no reason to be sympathetic towards Chinese when Chinese in America are already taking so many high paying tech jobs and slots at American elite schools, not to mention that they are also associated with a powerful enemy state on the other side of the world. If people like Iris Chang or Steve Hsu (or their parents) had well above average political skill or discernment, they would not have ended up in Taiwan or America in the first place. If they wanted to fight for the interests of Chinese, they would have joined the Communist Party of China instead, which understands that political power grows out of the barrel of a gun. In comparison, a Chinese-American who doesn't even know the Chinese language is basically a complete joke.
Chinese in America as a group are meant to excel in math and science and engineering and to a lesser extent business. But they do not have ruling class or conqueror genes. In contrast, they were the ones were voluntarily left or were forced out of their ancestral home country. Even worse, many are even delusional to think they are better than Chinese in China. Sure, some of the ethnic Chinese professors at top schools in STEM are in certain aspects of STEM. But STEM is only one aspect, especially for a group. But an actually powerful group needs a wide array of talents, skills, and personalities, which Chinese in America do not have. In fact in the other aspects, Chinese in America are a visible negative, like they don't even have their own language or military, not to mention all the infighting and lack of cohesion.
I hate to say it but as tense and full of hate China-America relations is right now, there is one thing that the two mainstreams might actually be able to genuinely cooperate on: political persecution of Chinese Americans. It's sad but true. Nobody wants them, and nobody likes them. They are unassimilable pretty much everywhere. I am sympathetic to their plight, especially the non-voluntary second gens, but if I had to make a serious decision, I would also reject them. At least, I would keep a bound on the closeness of my relation with them. Because it's obvious that Chinese in China have many contradictory interests and values with Chinese in America. In fact, I think in most cases, China should only accept Chinese Americans for politically subordinate positions where they actually have rare and valuable (not fraudulent) technical expertise to offer or in an exceptional case where the Chinese American has gone out of his way to politically prove himself. After all, that is what one would do if one has the slightest concept of political reliability in mind, which is, sadly, quite absent in many Chinese Americans.
