What follows is the sixth installment in a series explaining the context and deeper meaning of all eight songs on my band’s album all about Adam Smith “Silent Revolution.”  Listen to the entire album with audio commentary/explanation here. This song is inspired by text found in Section 1, Chapter 1 of Wealth of Nations.

The reason why certain nations get rich and others don’t is from a country’s ability to utilize the gains from specialization and division of labor. If we are all left to independently grow our own food, tend to our own wounds, or build our own airplanes, we’d all have a material standard of living dramatically less than what we have by participating in a commercial society. The “Robinson Crusoe” scenario is an extreme example showing how much we gain by having people focus on fewer tasks and work together to produce more with this same amount of inputs.

Smith was inspired by this picture in Denis Diderot’s Encyclopedie that showed the different stages of pin production.

Even in such a seemingly trifling trade, the tasks are split up between all the workers in a pin factory to significantly increase input.

One man draws out the wire; another straightens it…it is even a trade by itself to put them into paper; and the important business of making a pin is, in this manner, divided into about eighteen distinct operation, which, in some manufactories, are all performed by distinct hands…

Within a firm, division of labor increases output. Twenty people trying on their own and separately to do all tasks needed in pin production will surely turn out fewer pins in a given day than when they work together.

…But if they had all wrought separately and independently, and without any of them having been educated to this peculiar business, they certainly could not each of them, have made twenty, perhaps not one pin in a day; that is, certainly, not the…what they are at present capable of performing, in consequence of a proper division and combination of their different operations.

And within a society, specializing and utilizing division of labor increases output even more. A brain surgeon’s time is too valuable to force him or her to grow their own food and learn to program their computer. Instead, the brain surgeon goes to the supermarket where specialists in food production sell their services and resources. Or buys the iPhone that was programmed by the people who studied computer science.

It is the maxim of every prudent master of a family, never to attempt to make at home what it will cost him more to make than to buy.

The complete lyrics to Pin Factory:

From wire drawn until the straightening, pass through eighteen distinct hands
Ten people now could make more in a day than if left to do on their own
Cut then before put into paper, the pin comes out in completion
What seemed at first to be a trifling trade is revealed to greatly improve

And the master of a family knows this truth
That you don’t make at home what it costs less to buy

And the master of a family knows this truth
That you don’t make at home what it costs less to buy
