Mexican and Mexican American workers often earned more in the United States than they could in Mexico’s civil war economy, although California farmers paid Mexican and Mexican American workers significantly less than white American workers. By the 1920s, at least three quarters of California’s 200,000 farm workers were Mexican or Mexican American.
As this rapid shift of Mexico’s working population occurred, the first labor agreement between the United States and Mexico was formed. Mexico required that U.S. farm owners provide legal contracts for all Mexican workers guaranteeing conditions such as wages and work schedules. The U.S. government, in turn, enforced the border between the United States and Mexico, checking that all Mexican immigrants had the proper work contract so they would not be exploited.
As the Great Depression took a toll on California’s economy during the 1930s, however, Mexicans and Mexican Americans became targets for discrimination and removal. White government officials claimed that Mexican immigrants made up the majority of the California unemployed. White trade unions claimed that Mexican immigrants were taking jobs that should go to white men. In reality, a new supply of white refugees desperate for jobs was flooding California from the Midwest, making up the majority of the unemployed.
