The document discusses four individuals who worked to improve living and working conditions for the poor and working class in the late 19th and early 20th centuries:
Jacob Riis documented slum conditions in New York City through photography and writing, helping to establish laws against city slums. Williams Green advocated for union cooperation and helped pass laws establishing minimum wages and the 40-hour work week. Upton Sinclair's book "The Jungle" exposed unsanitary conditions in the meatpacking industry and influenced President Roosevelt to take "radical action". Laws were established similar to Britain's Poor Laws, offering aid to those able to work.
