In Sinclair Lewis's "Babbitt," the narrator acknowledges the imperfections within society and the ongoing need for improvement, particularly in the infrastructure of urban areas. The focus is on enhancing motor boulevards to facilitate better transportation and access for the growing middle class. This demographic, exemplified by individuals with moderate incomes and families, plays a crucial role in driving economic progress.

The quote emphasizes the dependency of societal advancement on the common man, particularly those who own automobiles and reside in suburban settings. These individuals represent the engine of progress, suggesting that their needs and lifestyles are integral to shaping the future of the community and its development.
