Let me tell you something, wherever Chinese goes, they are normally the smart and hardworking ones. Unless there is instituted discrimination, normally they are like Jews moving up the food chain. Hell, even with discrimination, they would move up the chain subtlety. It's just in the culture, we save for education and we work hard and have luckily an above average intelligence.
So when you tell me ethnic Chinese are failing behind, there can only be one reason, very serious discrimination. Btw, ethnic Chinese will always retain the surname no matter what name they put in front to blend in. It's the core of our identity, no matter where you go, your surname stays with you. Even your surnames were given by us to give you some civilization. So if a Chinese is surnamed Rossler, he is no longer Chinese to me.
