"Steinbeck's novel The Grapes of Wrath and the subsequent John Ford movie promulgated a populist mythology about depression-era migrants to California who were dubbed "Okies," no matter what southwestern or midwestern state they hailed from. But most Californians regarded Okies as dirty, shifty, lazy, violent, and ignorant."
