I am having a hard time to define success in this scenario. In this case there are extra data hidden in the question.
Imagine that we are the parents: We were raised to be honest, truthful, good willing, to have filotimo (or else we wouldn’t have the dilemma in the first place). It may have not made us billionaires but if we have managed to make a family of our own (<have children), possibly have a job (<means to support our lifestyle and children), obviously have a developed character (<being on fluther and discussing/sharing knowledge and opinions), and probably have things to look forward to/up to (<making plans for the future, thinking the best way to raise our children). Under this scope we are quite successful ourselves. We manage that mainly because we have judgement and the ability to distinguish (usually) right from wrong or least make decisions based on ethics. Even if a society is pure capitalist, there are elements of honesty and decency in it, or else there is no room for the society to develop; thus such a society has no future.
Taking these facts into account, what is the point of taking away from our children their (possibly) only chance to learn and understand positive life values? For the sake of them having one chance in the million to become overtly rich aka capitalistic successful?
