there will be no universal way

to educate children or to be successful. To be born in a poor, rich, middle-class famiy cannot be chosen by any child. As parents, poor or rich, should educate their children to be successful (depends on how to define).

That does not mean a successful parent will have or doomed to have a successful child. Nor a successful person must come from a successful family.

His post talk about how to educate children; i do not think he wants to solve the problem for every family of the society.
