With the prosperity of the era, the prevailing social attitude was one of belief in science, technology, progress, and futurism, although there had been signs of this trend since the 1930s. There was comparatively little nostalgia for the prewar era and the overall emphasis was on having everything new and more advanced than before. Nonetheless, the social conformity and consumerism of the 1950s often came under attack from intellectuals (e.g. Henry Miller's books "The Air-Conditioned Nightmare" and "Sunday After The War") and there was a good deal of unrest fermenting under the surface of American society that would erupt during the following decade.
