Babbitt by Sinclair Lewis.
Babbitt focuses on the titular character George Babbitt, a middle-aged real estate agent living in the fictional city of Zenith. Babbitt has attained a degree of social status and material comfort, but remains dissatisfied with his predictable, mundane life. Lewis depicts the vacuousness of America's emerging middle class through Babbitt's daily routine, his joining of various booster clubs, and his strained relationship with his family. Though Babbitt attempts minor rebellions, he ultimately capitulates to the pressure to conform. Lewis employs satire to critique the self-important complacency and lack of culture in bourgeois society. Ultimately, Babbitt remains trapped by Zenith’s social mores, unable to escape the monotony of his prescribed life. Lewis' scathing indictment of materialism and conformity sparked controversy upon its 1922 publication.
