The stockyards symbolize the plight of the common laborer, who is shuffled through the machinery of capitalism as a means to the end of corporate profit. Just as the stockyards are crammed with animals being herded to slaughter, so too are they packed with laborers systematically being destroyed by economic forces beyond their control. The factory owners have concern for the suffering of neither the animals nor the workers, viewing both as essential components of the meat-packing industry. In a sense, the laborers are nothing more than pieces of meat themselves—stripped of his identity, each laborer is merely a mass of muscles that, by helping the meat-packing plant run, factors into the general equation of consumption. Additionally, the crowded animal pens of the stockyards symbolize Packingtown’s crowded living quarters for workers. With almost no personal space or privacy for the individual, Jurgis and his family are dehumanized by their accommodations. Similar to an animal, Jurgis exists, from a severe capitalist point of view, only to carry out his function at the meat-packing plant.

In an effort to win converts to socialism, Sinclair constructs every formal element in as simple and transparent a way as possible. The narrative structure follows one long descent into the hellish reality of capitalism until Jurgis discovers socialism and is saved in a manner not unlike the evangelical Christian idea of being born again. Sinclair fleshes out this capitalist hell with a realistic style that relies heavily on stomach-churning description. Sinclair’s realism falters with his characters, however. At times, they seem less like portraits of realistic people and more like one-dimensional representations of particular classes and social forces. While abstract forces such as capitalism and socialism do shape and sometimes suppress individual identities, one can argue that there is a tension between the flatness of Sinclair’s characters and the human qualities with which he tries to instill them. Jurgis, for example, is called upon to represent an entire class of society and be a loving father, devoted husband, pitiful victim, and hero. He is asked to be a glorified abstraction and a particular person, but his role as representative of the proletariat seems to rob him of the real humanity that would make his struggle worthwhile. Along similar lines, the socialist characters exhibit a frightening degree of conformity and live with each other without antagonism or complexity. Their idealization runs seems somewhat at odds with the novel’s claim, implicit in its style and setting, of being realistic.
