Chicago was famously dubbed “Hog Butcher for the World” by Carl Sandburg in his iconic poem “Chicago.” The city was the center of America’s meatpacking industry for roughly a century, transforming the way livestock were sold, processed, transported, and eaten. Industrialist tycoons such as Philip Armour and Gustavus Swift created and then dominated an industry that changed Americans’ relationship to meat – and squeezed out massive profits at the same time. A century and a half after they first began processing “everything but the squeal” in Chicago, many of their abuses – an indifference to workers, health, the environment, or smaller business – are once again a part of the industry.
