From Fred Siegel. A quote:
Throughout the opening decades of the 20th century, American liberals engaged in a spirited critique of Americanism, a condition they understood as the pursuit of mass prosperity by an energetic but crude, grasping people chasing their private ambitions without the benefit of a clerisy to guide them. In thrall to their futile quest for material well-being, and numbed by the popular entertainments that appealed to the lowest common denominator in a nation of immigrants, Americans were supposedly incapable of recognizing the superiority of European culture as defined by its literary achievements.
This critique gave rise to the ferment of the 1920s, described by the literary critic Malcolm Cowley as the “exciting years…when…the young intellectuals seized power in the literary world almost like the Bolsheviks in Russia.” The writers Cowley referred to—Sinclair Lewis, F. Scott Fitzgerald, Sherwood Anderson, and Waldo Frank especially—had “a vague belief in aristocracy” and a sense that they were being “oppressed” by the culture of Main Street. But they believed America could be rescued from the pits of its popular culture by secular priests of sufficient insight to redeem the country from the depredations of the mass culture produced by democracy and capitalism. They were championed not only by leftists such as Cowley, but also by Nietzscheans such as H.L. Mencken, the critic and editor whom Walter Lippmann described in 1926 as “the most powerful influence on this whole generation of educated people” who famously mocked the hapless “herd,” “the imbeciles,” the “booboisie,” all of whom he deemed the “peasantry” that blighted American cultural life.
