War of the Classes by Jack London

War of the Classes is a powerful collection of political and social essays in which Jack London examines capitalism, labor struggles, class divisions, and the growing socialist movement of his time. Drawing from his own experiences among workers and the poor, London argues that economic inequality creates conflict between social classes and calls for greater justice and collective action. His writing combines personal observation, political conviction, and sharp criticism of industrial society. The book offers valuable insight into early twentieth-century socialist thought, labor politics, and social reform, while revealing another important dimension of London beyond his famous fiction and adventure stories.
