Off the Books: The Underground Economy of the Urban Poor 
In this revelatory book, Sudhir Venkatesh takes us into Maquis Park, a poor black neighborhood on Chicago's Southside, to explore the desperate, dangerous, and remarkable ways in which a community survives. We find there an entire world of unregulated, unreported, and untaxed work, a system of living off the books that is daily life in the ghetto. From women who clean houses and prepare lunches for the local hospital to small-scale entrepreneurs like the mechanic who works in an alley; from the preacher who provides mediation services to the salon owner who rents her store out for gambling parties; and from street vendors hawking socks and incense to the drug dealing and extortion of the local gang, we come to see how these activities form the backbone of the ghetto economy.
What emerges are the innumerable ways that these men and women, immersed in their shadowy economic pursuits, are connected to and reliant upon one another. The underground economy, as Venkatesh's subtle storytelling reveals, functions as an intricate web, and in the strength of its strands lie the fates of many Maquis Park residents. 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.
Reviews
...unless you already live in a highly urbanized/disadvantaged neighborhood.
The author is an enterprising young academic who is drawn to the firsthand study of life in such neighborhoods. Being of mixed race "gave me (the author) an indeterminate and unthreatening presence" by which he could spend months with the residents - enough time to understand life and the economy there with more thoroughness than perhaps ever before.
The underground economy in this corner of America is woven into every fabric of life. You learn first hand about enterprises running the gamut from the homeless fellow who does reliable auto repair in back alleys and side streets, to the (no surprise here) sex workers and drug sellers, to the stay at home mom that cooks meals for local residents, shopkeepers and even the police.
You learn how the local gang leader is not simply a lawless soul feared by all, but a broker of influence upon which even the most upstanding residents come to rely.
With so much disadvantage built into the neighborhood you come to understand how everyone learns to accept shady economic dealings out of the joint recognition of the need to survive. But when such dealings bring a larger than acceptable threat to the children and residents, then the gang leader is often brought in to broker a deal to return things to homeostasis.
As a white suburbanite here is what struck me the most. There is waaaaay more tolerance and acceptance among neighbors in the ghetto than there is in suburbia. There is waaaaay more neighbor involvement and mutual reliance in the ghetto than in suburbia. In fact, instead of the ongoing competition so often found in the suburbs, the ghetto is characterized by the opposite - genuine concern for and involvement with one's neighbors.
Is it a great place to live? Of course not. I mean, any world where you have to call on the gang leader to broker safety in the streets for kids must be a risky world.
But as the book will teach you, there is a richness, mutual acceptance, and mutual protection that would be envied in the safer suburbs. Not to mention a level of economic enterprise that outsiders - until now - had no idea existed.
As I said at the beginning, some books teach you additional things about something you already know. This book teaches you about something (you will admit by page 10) you almost certainly know nothing.
