"A People's History of the United States" stands out because it focuses on the experiences and struggles of ordinary people rather than political leaders. Howard Zinn highlights the contributions and resistance of marginalized groups, offering a more inclusive perspective on American history.

The book discusses various marginalized groups, including Native Americans, African Americans, women, and laborers. Zinn documents their resistance movements and contributions, emphasizing their role in shaping American history.

Economic inequality is a significant theme because Zinn explores how wealth and power have historically been concentrated in the hands of a few, often at the expense of the working class and poor. By examining labor strikes and economic policies, the book highlights the persistent issue of economic inequality and its impact on society.
