"In the United States, it is now possible for a person eighteen years of age, female as well as male, to graduate from high school, college, or university without ever having cared for, or even held, a baby; without ever having looked after someone who was old, ill, or lonely; or without ever having comforted or assisted another human being who really needed help... No society can long sustain itself unless its members have learned the sensitivities, motivations, and skills involved in assisting and caring for other human beings."
