I also disagree with D'Souza's assertion that the poor parts of black America can only change from within. I hate the thought of our waiting around for some kind of new leadership to emerge, or spontaneous community development to take place, while kids are getting shot outside their homes. During the past decade putting more police out on the streets has reduced crime in many black neighborhoods. That's not change from within. Schools can be made better from without.
Employment can come from without.
Public housing can be made safe and secure via policy decisions made far away. If our whole society would evince a sense of urgency, concern, and responsibility about the underclass, the result would be both a better life for the underclass and better race relations generally.
