Upton Sinclair 
The Jungle 

Upton Sinclair’s most famous novel, ‚The Jungle‘ is the fictitious account of a family of Lithuanian immigrants living in Chicago and working in the Chicago’s Union Stock Yards. While it is a work of fiction it brought to light the horrible working conditions of the Chicago meat-packing industry at the beginning of the 20th century. Sinclair, a noted socialist, showed the vast socio-economic divide between the haves and have-nots and the corrupt alignment of American politicians with the industrial-capitalist machine.
