That is why I said if you look closely you will not find such generic assertions. Another example is that Adam Smith realized how much efficiency can by gained by division of labor but he also said that this leads to inhuman labor conditions and should be avoided. But what is our reality? We pick the efficiency gain and ignore the negative effects as long as we can. If workers start complaining we do the bare minimum, rotate them through a couple of different tasks, but that is obviously far from trying to avoid division of labor as much as possible.
