Social progress has done away with the need for backbreaking work and has provided time and leisure for personality development. With it, indeed because of it, today the middle-class family expects each of its members to develop his unique personality, and so does each individual, more or less, himself. This new- obligation of the family to provide a setting for the development of a unique personality makes family consensus extremely difficult, if not impossible. Nothing is more problematic for a small group of quite different, unique individuals than to live in close quarters, in close harmony with each other. Besides, the necessity of cultivating teenagers’ moral character adds to the difficulty in parenting.
