In 1942, the final report on the CCC noted that "Enrollees lived two hundred in a camp. Living together in barracks with other young men taught enrollees to respect the rights of others and to be tolerant of their ideas and beliefs... The funds expended to divert the energies of idle youth to useful work in the public interest paid the Nation enormous dividends" (Federal Security Agency, Final Report of the Director of the Civilian Conservation Corps, April, 1933 through June 30, 1942, pp. 81 and 88, emphasis added).
