"While Superman was a complex conglomeration of influences, Jerry and Joe left plenty to reader’s imaginations. What Superman “wasn’t” was just as important as what he was. The character had no clear ethnic background, no hint of an accent or dialect, no stated religious preference, and no political affiliation. The Superman character offered a little bit to everyone. Coming from a distant planet, he was the ultimate foreigner. Raised in the Midwestern heartland, he was the quintessential American. Growing up in a small town, he was rural at heart. Moving to a big city, he became more sophisticated and worldly. He was both weak and strong. Hi meek, mild alter ego, Clark Kent, was a sheepish bumbler, but he was always ready to transform himself into the all-powerful superhero. So Superman was relevant to the prairie farmer, the urban factory worker, the white-collar insurance salesman, the hardworking waitress, and the struggling immigrant. Millions or ordinary people struggling through the Depression could imagine themselves shedding their plain, run-of-the mill exteriors to reveal their real power within. True, Superman had descended from the heavens with the power of a god. His intention was godly too-to protect humanity from its own worst instincts. But Superman had characteristics the masses could relate to. He could beam with a smile, burst into anger, and form lasting friendships. Beneath it all Superman seemed like a regular guy. Superman was also a creation of his times. To keep up with those times, Jerry and Joe often spent Saturdays flipping through out-of-town newspapers and national newsmagazines for ideas at the Cleveland Public Library. The headlines described crisis after crisis. The New York Stock Exchange had lost 90 percent of its value Millions of Americans were out of work, a Midwestern drought had engulfed prairie farms in the Dust Bowl, and desperate farmers had to pack up their starving families and head to California to start anew. The international news was no more comforting. Headlines warned of economic collapse in global markets, the rise of fascist regimes in Europe, and the new communist experiment in the Soviet Union. The whole world seemed to be heading toward an explosion."
