What was the one major problem in the Progressive Era?

One major problem during the Progressive Era was the widespread racial discrimination and segregation, particularly against African Americans. Despite the movement's focus on social reform and improving conditions for many, significant racial inequalities persisted, exemplified by Jim Crow laws in the South. This era often overlooked or sidelined the rights and needs of minority groups, highlighting a crucial limitation in the broader reform efforts aimed at achieving social justice and equality.
