JOLIET, Ill. -- It's a typical weekday afternoon at the intersection of Route 53 and Laraway Road, 40 miles southwest of Chicago, and semitrucks thunder by in a steady stream. They start at the sprawling warehouse complexes on the fringes of the city of Joliet, rumble alongside the fading polyester petals of a roadside memorial for someone who died in a truck crash and roll past the ball fields where youth teams play, carrying goods for Amazon, Ikea, Walmart, Target and Dollar Tree.
