Did the benefits of American expansion outweigh the costs?

The benefits of American expansion, such as economic growth, increased territorial control, and the spread of democratic ideals, significantly contributed to the nation's development. However, these gains came at substantial costs, including the displacement and suffering of Indigenous populations, conflicts like the Mexican-American War, and the intensification of slavery-related tensions. Ultimately, whether the benefits outweighed the costs is subjective and depends on one's perspective on issues like human rights and national identity. The complexities of this expansion continue to influence American society and politics today.
