Did You Know?
The values, attitudes, and mores associated with the American middle class in the 1920s can be summed up in the word Babbitry. It derives from the protagonist of Babbitt, a satirical novel by Sinclair Lewis published in 1922. George F. Babbitt epitomizes the unimaginative and self-important businessmen that Lewis found typical of the provincial cities and towns of America. Despite his evident prosperity and status, he remains vaguely dissatisfied with life and makes tentative attempts at rebellion; however, in the end, he finds his need for social acceptance greater than his desire for escape.
