Why did Californians did not welcome the Plains migrants?

Californians were often unwelcoming to Plains migrants due to competition for resources, such as jobs and land, especially during times of economic hardship. Many established residents feared that the influx of migrants would strain local economies and lead to increased social tensions. Additionally, cultural differences and negative stereotypes contributed to a sense of distrust and hostility toward the newcomers. This resistance was compounded by the social and political climate of the times, which often favored native-born residents over migrants.
