I think it extends pass wanting their children to be good at their jobs.

“The Chinese believe that the best way to protect their children is by preparing them for the future, letting them see what they're capable of, and arming them with skills, work habits and inner confidence that no one can ever take away."

I don't think any parent would want their children to be unable to make something for themselves. But the point is their approach and what it says about the culture.
