Surely children are not born knowing right and wrong?

Children are not born knowing right and wrong arises out of the paternalist view of children, which mistakenly holds that children learn moral knowledge through coercion, and that no one would have any interest in improving their moral knowledge unless forced to do so. But actually, coercion impedes and impairs learning, including of moral knowledge, and the vast majority of people including children are trying to do the right thing and trying to improve, including morally, and no one has perfect moral knowledge.

Requiring children to do chores

Parents often believe that their financial support and other services for their children morally obliges the children to provide certain services in return. But there is no justification for that belief. It is just a rationalisation of the traditional status quo between parent and child. The truth is that there is a moral asymmetry between parent and child: in the event of an intractable dispute between them, the parent chose to place the child in the situation that caused the dispute; the child did not choose to place the parent there.
