The basis of all morality is duty, a concept with the same relation to a group that self-interest has to individual. Nobody preached duty to these kids in a way they could understand — that is, with a spanking. But the society they were in told them endlessly about their ‘rights.’ The results should have been predictable, since a human has no natural rights of any nature.
