Nowadays all countries only pay attention to the academic, they never pay attention to the moral education anymore
They shouldn't. That is a responsibility of a parent and no one can objectively tell you what is moral and what is not.
Moral education supposed to be taught at school and the parents also need to responsible to teach their children, moral education can make the world become better place to live
Moral education is nothing more than training a person to be obedient to your values and beliefs without any reasonable explanation.
If it makes sense to do something, then it can be thought scientifically, but if you have no proof, no evidence and no reasoning to act a certain way, that is just brainwashing an individual to blindly follow your instructions.
If it's the responsibility of the parent, and the parent received no moral education, then where are the morals going to come from? How can we decide on a decent set of values and beliefs if we leave it up to the subjective will of the parents to decide? What if one family's values conflict with another's? Then how are we going to find a middle ground if these issues are not addressed in education? Who will mediate?
Education does not have to be brainwashing. It can be balanced and tolerant.
