The novel is critical of American society and its treatment of its citizens, many of which Vonnegut writes "were so ignored and cheated and insulted that they thought they might be in the wrong country." He focuses largely on race, the poor, and the destruction of the environment, criticizing the hypocrisy of a land that claims to be based on the principles of freedom having been founded by people who "used human beings for machinery, and, even after slavery was eliminated, because it was so embarrassing, they and their descendants continued to think of ordinary human beings as machines." The incidents in the life of Wayne Hoobler, a black resident of Midland City, are frequently contrasted with those of the similarly named Dwayne Hoover, emphasizing the aforementioned impact of race.
