You Can't Win is an autobiography by burglar and hobo Jack Black, written in the early to mid-1920s and first published in 1926. The book tells of Black's experiences in the hobo underworld, freight-hopping around the western United States and Canada, with the majority of incidents taking place from the late 1880s to around 1910. He tells of becoming a thief, burglar, and member of the yegg (safe-cracking) subculture, exploring the topics of crime, criminal justice, vice, addictions, penology, and human folly from various viewpoints, from observer to consumer to supplier, and from victim to perpetrator.
