dispute

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.
