in the blue tights and red cape". An influence on early Superman stories is the context of the Great Depression. Superman took on the role of social activist, fighting crooked businessmen and politicians and demolishing run-down tenements. Comics scholar Roger Sabin sees this as a reflection of "the liberal idealism of Franklin Roosevelt's New Deal", with Shuster and Siegel initially portraying Superman as champion to a variety of social causes. In later Superman radio programs the character continued to take on such issues, tackling a version of the Ku Klux Klan in a 1946 broadcast, as well as combating anti-semitism and veteran discrimination. Scott Bukatman has discussed Superman, and the superhero in general, noting the ways in which they humanize large urban areas through their use of the space, especially in Superman's ability to soar over the large skyscrapers of Metropolis. He writes that the character "represented, in 1938, a kind of Corbusierian ideal. Superman has X-ray vision: walls become permeable, transparent. Through his benign, controlled authority, Superman renders the city open, modernist and democratic; he furthers a sense that Le Corbusier described in 1925, namely, that 'Everything is known to us'." Jules Feiffer has argued that Superman's real innovation lay in the creation of the Clark Kent persona, noting that what "made Superman extraordinary was his point of origin: Clark Kent." Feiffer develops the theme to establish Superman's popularity in simple wish fulfillment, a point Siegel and Shuster themselves supported, Siegel commenting that "If you're interested in what made Superman what it is, here's one of the keys to what made it universally acceptable. Joe and I had certain inhibitions… which led to wish-fulfillment which we expressed through our interest in science fiction and our comic strip. That's where the dual-identity concept came from" and Shuster supporting that as being "why so many people could relate to it". Ian Gordon suggests that the many incarnations of Superman across media use nostalgia to link the character to an ideology of the American Way. He defines this ideology as a means of associating individualism, consumerism, and democracy and as something that took shape around WWII and underpinned the war effort. Superman, he notes was very much part of that effort. An allegory for immigrants Superman's immigrant status is a key aspect of his appeal.Engle, Gary "What Makes Superman So Darned American?" reprinted in Popular Culture (1992) Popular Press p 331–343.
