Adam Smith, a writer in the 1700s, was the first person to see the importance of the divis
Ten men, Smith said, in this way, turned out twelve pounds of pins a day or about 4 800 pins a person. But if all of them had worked separately and independently without division of labor, they certainly could not turn out any pin, each of them would have made twenty pins in a day and perhaps not even one
There can be no doubt that division of labor is an efficient way of organizing work. Fewer people can make more pins. Adam Smith saw this but he also took it for granted that division of labor is in itself responsible for economic growth and development and that it accounts for the difference between expanding economies and those that stand still. But division of labor adds nothing new: it only enables people to produce more of what they already have.
