While the powerlessness of the laboring class is a recurring theme in Steinbeck's work of the late 1930s, he narrowed his focus when composing Of Mice and Men (1937), creating an intimate portrait of two men facing a world marked by petty tyranny, misunderstanding, jealousy, and callousness. But though the scope is narrow, the theme is universal; a friendship and a shared dream that makes an individual's existence meaningful.
