Pretty simple really. Most start off more highly paid than most - but the pay difference drops off over time. Most lead unassuming, mundane existences.
A large portion live with the nagging dissatisfaction that they struggled so much harder than everyone else, sacrificed so much more, and yet somehow the payoff doesn't seem commensurate. They were at the top end of the distribution all their life, but now practically define normality.
Most will look around them and realize it could be much worse - they could be running a laundromat. They will then quietly accept their mundane, normal, and honestly, somewhat boring existence in good grace.
Some cannot get over the fact that they threw their childhood, adolescence, and prime years away for a shot at mediocrity. Some have become miserable in this process - this goes double for those who had a real passion for something off the beaten Asian track (art, literature, music, etc). Some of these people will eventually crack and throw it all away to pursue what they actually wanted to do.
If they fail, they will be used as examples on why straying from The Path(tm) is unwise.
If they succeed, they will be praised and looked upon in admiration as a triumphant success of the immigrant community. They will, ironically, be used as examples of how It Works(tm) whenever this exact issue comes up in conversation.
