Confronted with the unhappy facts of exclusion, we sometimes reassure ourselves by telling stories: the poor boys who made it, theblacks who became a "credit to their race," the women elected to high office, the handicapped who made "useful contributions" to our society.... Just as we believe in the self-sufficient family, we also believe that any child with enough grit and ability can escape poverty and make a rewarding life. But these stories and beliefs clearly reflect the exceptions.
