This is not a consensus, not even a conclusion.
The world is too big for us to understand every aspect of it, not to say 2 guys familiar to a same subject may probably hold contrary opinions.
There are also many other professors in US commenting on how things are going outside US, correctly or not.So take it easy.
There is a difference between intelligence and intellectual-ism.
Americans are no different than any other people. Parents want their children to be intelligent and for when the children became adults, they would have intelligent spouses.
But perhaps what make Americans somewhat unique, and that uniqueness disgusted the great sci-fi writer Isaac Asimov, is that Americans are suspicious of intellectual-ism, which is:
- the exercise of the intellect at the expense of the emotions.
That does not mean we cannot look at things in objectivity (emotionless), but rather that we are suspicious of anyone who is constantly that way and who continually advocates living that way. Of all the professions, the one that values emotional living is the medical profession. Doctors know full well how emotions affects brain chemistry and we know more about the Moon than we do about the human brain/mind combination.
Suspicions of intellectual-ism and intellectuals are not confined to Americans even though we may make that suspicion more obvious than others. Here is what your Mao said of intellectuals during the Anti-Rightist Campaign of 1957-59:
'An intellectual has a tail just like a dog, if you pour some cold water on it, he will tuck it between his legs, but if you try a different attitude he will wag it high in the air, and he will look quite cocky. Just because he has read a couple of books he feels quite cocky. When working people see his cocky air, when they see that attitude, they feel a little uncomfortable.'
Chinese intellectuals were persecuted, not just by the state but also by the people after Mao conjured up all sorts of characters unique to anyone who had any level of academic learning and how those character traits made them 'enemy of the people'. Mao could not have done this unless there is an existing suspicion of intelligent people who are not intellectuals in the first place. Mao, just like Hitler and other great charismatics in history, understand people, their weaknesses, and vulnerable points.
So take it easy on US.
