People in impoverished cities, for example in Kinshasa, lend small quantities of food to neighbors when requested, to prevent starvation. In Mumbai, they share their living space with others who are homeless. In Detroit, churches and the Detroit Urban League have helped poor residents to obtain jobs, meals, and housing. Rather than mere self-interest, this expression of generosity is an outstanding human quality. Networks of survival also include the lessons of history, good economic and political policies, human rights, equal opportunity, and culture.
