The U.S. faces a critical challenge in its treatment of young people, as highlighted by the speaker at TED 2024. This issue encapsulates broader threats such as inequality, climate change, and conflicts in the Middle East. The speaker emphasizes that a society's success can be gauged by how it cares for its children, which reflects the effectiveness of its structures and leadership. The traditional American belief in upward mobility has been shattered, with today's youth earning less than previous generations while burdened with unprecedented student debt.
