In the book "Main Street" by Sinclair Lewis, the author reflects on the nature of human troubles, suggesting that many of them are self-created and avoidable. While humanity has mastered the environment to grow crops and withstand severe weather, it seems we still find ways to complicate our lives. Instead of addressing essential needs, we engage in conflicts and disputes that arise from politics, races, and social issues, indicating a tendency to create chaos for our own amusement.

This commentary highlights a contrast between our ability to conquer nature and our penchant for generating conflict amongst ourselves. The author argues that while we have overcome many challenges offered by the natural world, we often choose to entertain ourselves with strife that leads to unnecessary suffering. This idea invites readers to reconsider where they focus their energy and the real sources of their troubles, prompting a reflection on the human condition and our choices.
