Final answer:
Racial prejudices magnified the effects of the Great Depression for African Americans and Mexican Americans through discriminatory hiring practices, restricted access to government relief programs, and increased racial violence and discrimination.
Step-by-step explanation:
Racial prejudices magnified the effects of the Great Depression for African Americans and Mexican Americans in a number of ways. First, discriminatory hiring practices resulted in job losses and reduced income. Many employers favored White workers over African American and Mexican American workers, further exacerbating the economic hardships they faced. Second, access to government relief programs was restricted based on race. African Americans and Mexican Americans were often denied or received limited assistance compared to their White counterparts. Third, racial violence and discrimination increased, further deepening the economic hardships faced by African Americans and Mexican Americans during the Great Depression.
