What aspect of American life does Sandburg's poetry often focus on?

Carl Sandburg's poetry often captures the essence of urban life in America, particularly in the early 20th century. His work vividly portrays the complexities of city life, delving into themes such as the hustle and bustle of urban existence, the stark realities of industrialization, and the diverse experiences of the working class. Sandburg’s most famous work, "Chicago," exemplifies this focus, celebrating the city's raw energy while also addressing its challenges and grit. Through his use of lively imagery and personification, he brings to life the vibrancy and struggles inherent in the urban landscape, making it a central theme in his poetry.

In contrast, while beauty in nature and the struggles of rural farmers are subjects touched upon by some poets, they do not hold the same pivotal role in Sandburg's body of work as the complexities of urban life do. Additionally, the history of American literature, although significant in understanding Sandburg's context, is not a primary focus of his poetry.
