This book is a study of jails and I personally feel like this is an important study. I feel like this book should be read by the public and policymakers. Irwin demonstrates how poverty and inequality created a population that was processed by the courts and jails into underclass “rabble”. The most vulnerable population, through repeated terms in The Jail, is transformed into the rabble. The thesis of the book is that the jails prepare the poor to be an underclass. This book should be read by anyone interested in understanding why homelessness and petty crime have become a feature of every major city. We all should be more aware, because the many people who talk about the crime problem, throughout the cities, have very little knowledge about what happens behind the “systems” walls.
