American cold war culture represented an age of anxiety. The anxiety was so severe that it sought relief in an insistent, assertive optimism. Much of American popular culture aided this quest for apathetic security. The expanding white middle class sought to escape their worries in the burgeoning consumer culture. Driving on the new highway system in gigantic showboat cars to malls and shopping centers that accepted a new form of payment known as credit cards, Americans could forget about Jim Crow, communism, and the possibility of Armageddon. At night in their suburban homes, television allowed middle class families to enjoy light domestic comedies like The Adventures of Ozzie and Harriet, Father Knows Best, and Leave It to Beaver. Somnolently they watched representations of settled family life, stories where lost baseball gloves and dinnertime hijinks represented the only conflicts. In the glow of a new Zenith television, it became easy to believe that the American dream had been fully realized by the sacrifice and hard work of the war generation.
American monsters in pop culture came to the aid of this great American sleep. Although a handful of science fiction films made explicit political messages that unsettled an apathetic America, the vast majority of 'creature features' proffered parables of American righteousness and power. These narratives ended, not with world apocalypse, but with a full restoration of a secure, consumer-oriented status quo. Invaders in flying saucers, radioactive mutations, and giant creatures born of the atomic age wreaked havoc but were soon destroyed by brainy teams of civilian scientists in cooperation with the American military. These films encouraged a certain degree of paranoia but also offered quick and easy relief to this anxiety... Such films did not so much teach Americans to 'stop worrying and love the bomb' as to 'keep worrying and love the state.
