What is the role of a child in this society?
The role of a child in this society should be first and foremost a gatherer of knowledge. Of course there are many roles a child can play. From entertainer to family and friends; as a helper to parents, family and society; to a servant of others. Children should not bear hard or even semi hard labor, as they are not mentally equiped to endure hardships of life at this age.
