Reading that article left me feeling a bit appalled.
One side of the spectrum there is sloppy and lazy parenting where parents don't give a shit about what their kids do, and on the other there is super-strict control freak parenting where children are treated like slaves who are forced to dance to their masters tune. The best parenting is the median between these extremes.
But furthermore, those Chinese kids are going to go to college, with their straight A's, to mix with Western students who were also bright enough to get into that same college as them, but actually had a happy childhood anyway. Consequently, i would expect them to be better rounded persons, whom have gone to college to study a subject they chose for themselves rather than what their parents chose for them, and gone through their teenage years attending parties, making friends and girlfriends and riding the highs and lows of life. My impression from the article is that these Chinese kids are sheltered from all these experiences and would struggle to live in an environment with these more socially experienced people.
