Let’s say you spent 250 years under a false name. That is exactly what happened in Adam Smith’s book. Everyone refers to it as the “Treasure of Nations,” and certainly, that’s a reasonable summary for those who know and those who just do. But for politicians and academics, it turns a rigorous intellectual inquiry into a giant sticker that distorts what the book is about.
This book was first published on March 9, 1776. Later that year, a “group of farmers” in the British American colonies had their own ideas and fundamentally changed the world. It is worth asking a simple question: what does Smith do actually write?
The full title is An Inquiry into the Nature and Causes of the Wealth of Nations. It’s a mouthful, but the difference between a full article and an abstract is more important than people realize.
First, let’s look at the word “Investigation.” Contrary to what many have said, Smith was not a preacher The Treasure of Nations that markets and capitalism work. He asked honest questions: why are some nations rich while others are poor? Why do some nations get rich while others stagnate or decline? In fact, all economics are about these questions, even indirectly. Nobel laureate Bob Lucas once said, “when you start thinking [economic development]it’s hard to think of anything else.” This concern is why Adam Smith is (rightly) called the “father of economics.”
Next, the choice of the word “Environment” in the title is illustrative. Smith also asks the question, “What is wealth?”
Before Adam Smith, most people and governments thought that wealth was measured in gold. After all, if having a lot of money makes a family rich, then it is clear that if nation you have more money, the nation will be richer, too. The goal was clear: fill your coffers with gold (read: money), promote exports so that other countries send gold to pay for your exports, and impose import restrictions, to avoid exporting your gold. This was the common wisdom of “mercantilism,” but it is nothing more than a creative illusion.
Smith brilliantly pointed out the problems with the mercantilist understanding of wealth. Wealth does not mean how much money you have. Wealth is about access to goods and services that people want or need. It’s about the food we can buy and the clothes we can wear. Money is only useful if we can exchange it with other people for things we need. Robinson Crusoe would not have had an easy time on his island if he had washed ashore with a billion dollar coin in his pocket.
After Smith sets out what wealth is (and isn’t), we are ready to understand its “Causes”. If wealth is about access to goods and services, what makes wealth increase? Smith describes it in the first chapters of the book: the division of labor. The nail industry that Smith uses to illustrate this is not only a good example, it shows that wealth is created by ordinary people doing special jobs. Disrupting that process destroys value rather than creating it.
But what causes the separation of labor? For Smith, that’s simple: exchange. A voluntary, mutually beneficial exchange that occurs when people are left to do what they like. And in the right institutional context, the exchange that people make is, in his famous phrase, “led by an invisible hand” to improve society, even if no one making that exchange ever intends to pursue that outcome.
An Inquiry into the Nature and Causes of the Wealth of Nations it’s a research program, not a slogan. Smith never declares that markets work. He investigates the conditions under which they do (and don’t). In this process, he offered one of the most important arguments in intellectual history: Wealth is not taken, determined, or accumulated. Given the right institutional setting, of course produced it’s ordinary people doing ordinary business with each other, working together to create something that no average producer could have designed or understood.
Two hundred and fifty years later, that research program is still ongoing. Policymakers—and many others—still confuse wealth, mistake the treasury and stock market for the economy, and believe that prosperity can be created by limiting competition and rewarding favored industries. Smith found problems with these beliefs in 1776.
Today, the need to read (and re-read) Smith has never been greater. We should start with the title.
