I read that in an interview with Henry Ford, the interviewer tried to get Ford to justify why his labor costs were higher than other automakers and Ford stopped him and said his labor costs were actually the lowest, per unit. Also same article said the pace of work in Ford factories was brutally unsustainable. Which might also be why he went to an 8 hour work day.
