When World War II began, large amounts of money went flooding to California to aid the USA in the war. This was great for the Okies, more jobs, better jobs, opened up and they were able to make their lives better over time. Other Okies saw this and decided they wanted to go to California to make even more money. An oil worker wanted to make enough money to go back to Oklahoma and buy a farm, another family wanted to rent out their farm while they were away to potentially double their earnings. These families that came during the 1940s lived in California's biggest cities, Los Angeles, San Diego and various cities in the San Francisco Bay Area. Other families who moved to California before had moved to the valleys and rural areas.
