The Jungle

"They use everything about the hog except the squeal."
--- Upton Sinclair, The Jungle

The Jungle is a 1906 novel written by author and socialist journalist Upton Sinclair. It was written about the corruption of the American meatpacking industry during the early 20th century. The novel depicts in harsh tones the poverty, absence of social programs, unpleasant living and working conditions, and hopelessness prevalent among the "have-nots", which is contrasted with the deeply rooted corruption on the part of the "haves".
