The perception that people who live in small towns are smug isolationists, and that this attitude erodes the quality of their aesthetic judgement, is a well-known starting point for satire in books and movies. Read, for example Sinclair Lewis’s characterization of typical small town life in his 1920 novel Mainstreet


It is dullness made God. A savorless people, gulping tasteless food and sitting afterward, coatless and thoughtless, in rocking-chairs prickly with inane decorations, listening to mechanical music, saying mechanical things about the excellence of Ford automobiles, and viewing themselves as the greatest race in the world." 22-III, 257-258 Main Street, 1920
