Well researched muckraker. The book offers an intersting History of Immigration and the conditions in Chicago around the turn of the century. This book never did accomplish the motive of Sinclair to reveal the deplorable working conditions in the meat packing industry. It did however force Roosevelt to push Congress to adopt the Pure Food and Drug Act along with the Meat Inspection Act. For that alone, its stands the test of time. It reads well and I found it hard to put down.It did drag a bit through the last few chapters which focused on Socialism.
