"Poor children live in a particularly dangerous world--an urban world of broken stair railings, of busy streets serving as playgrounds, of lead paint, rats and rat poisons, or a rural world where families do not enjoy the minimal levels of public health accepted as standard for nearly a century. Whether in city or country, this is a world where cavities go unfilled and ear infections threatening permanent deafness go untreated. It is world where even a small child learns to be ashamed of the way he or she lives."
