Most white-collar workers wear white collars, but they’re still working in the factory. They push a pencil or process an application or type on a keyboard instead of operating a drill press. The only grease they have to get off their clothes at the end of the day is the grease from the take-out food at lunch. But it’s factory work. It’s factory work because it’s planned, controlled, and measured. It’s factory work because you can optimize for productivity. These workers know what they’re going to do all day—and it’s still morning.
