for example in china some dude finishes college.  he is judged in a massive way by society what college it was, how much does he earn, what is his status in society, when will he have children and pedegree is his wife? does he have a house, what are his future financial prospects, who are his friends and so on and on...  he needs to pretend to care about all of this, all his peers need to do it. he is judged by a lot of people on it and there is a whole monetary class system in china. communism tried to eradicate it but it never went away because money just became prestige and now it's back to money.  so what are his options? well he can move somewhere else and literally have none of this. nobody cares what his college degree is in the us, he knows nobody and nobody has any expectations of him. if he makes new friends and it's a lot easier to make them in the us. he will have a happier social and mental life then living in well manicured china.
