What internal problems did the US experience during the 1900s?

During the 1900s, the United States faced significant internal problems including economic inequality, labor disputes, and racial tensions. The rise of industrialization led to harsh working conditions and the formation of labor unions, which often resulted in strikes and violent confrontations. Additionally, racial segregation and discrimination, particularly against African Americans in the South, fueled social unrest and spurred the Civil Rights Movement. Political corruption and the challenges of Immigration also contributed to societal divisions and discontent.
