A number of Franklin D. Roosevelt's New Deal agencies tried to help the rural poor to better themselves and to break through the social barriers of Southern society which held them back, reinstating the American Dream of upward mobility. Programs such as those of the Subsistence Homesteads Division of the Department of the Interior; its successor, the Resettlement Administration, whose express purpose was to help the poor in rural areas; and its replacement, the Farm Security Administration which aimed to break the cycle of tenant farming and sharecropping and help poor whites and black to own their own farms, and to initiate the creation of the communities necessary to support those farms. The agencies also provided services for migrant workers, such as the Arkies and Okies, who had been devastated by the Dust Bowl – the condition of which was well-documented by photographer Dorothea Lange in "An American Exodus" (1939) – and been forced to take to the road, jamming all their belongings into Ford motorcars and heading west toward California.
