Free Air
From a critical perspective, Free Air is consistent with Sinclair Lewis's lean towards egalitarian politics, which he displays in his other works (most notably in It Can't Happen Here). Examples of his politics in Free Air are found in Lewis's emphasis on the heroic role played by the book's protagonist, Milt Dagget, a working class everyman type. Conversely, Lewis presents nearly every upper-class character in Claire Boltwood's world (including her railroad-mogul father) as snobby elitists. The story also champions the democratic nature of the automobile versus the more aristocratic railroad travel. Lewis's emphasis on the freedom which automobiles would eventually give the working and middle classes bolsters the egalitarian, democratic aesthetic. Free Air is one of the first novels about the road trip, a subject around which the Beats (most notably Jack Kerouac) would build a cult following in the mid-20th century.
