Factory Wages: The Mean is Not the Average
The National Employment Law Project’s (NELP) study about American factories contains conclusions that equate the state of the auto parts industry with U.S. manufacturing as a whole. In philosophy, confusing the part with the whole is known as the fallacy of composition. On the factory floor, finding a bad part in a big batch is known as quality assurance. So is the NELP study flawed, or is it a fine example of QA?
