Book excerpt: In this revelatory book, Sudhir Venkatesh takes us into Maquis Park, a poor black neighborhood on Chicago's Southside, to explore the desperate and remarkable ways in which a community survives. The result is a dramatic narrative of individuals at work, and a rich portrait of a community. But while excavating the efforts of men and women to generate a basic livelihood for themselves and their families, Off the Books offers a devastating critique of the entrenched poverty that we so often ignore in America, and reveals how the underground economy is an inevitable response to the ghetto's appalling isolation from the rest of the country.
