"The decline in opportunity to play has also been accompanied by a decline in empathy and a rise in narcissism, both of which have been assessed since the late 1970s with standard questionnaires given to normative samples of college students. Empathy refers to the ability and tendency to see from another person’s point of view and experience what that person experiences. Narcissism refers to inflated self-regard, coupled with a lack of concern for others and an inability to connect emotionally with others. A decline of empathy and a rise in narcissism are exactly what we would expect to see in children who have little opportunity to play socially. Children can’t learn these social skills and values in school, because school is an authoritarian, not a democratic setting. School fosters competition, not co-operation; and children there are not free to quit when others fail to respect their needs and wishes."
