237 years ago Adam Smith published a book called An Inquiry into the Nature and Causes of the Wealth of Nations. Today there’s a great deal of debate about how to produce economic growth, jobs, income gains, and so forth. If we want to know the right answers, we should start with the title of Smith’s book. It contains two insights: that some nations are wealthy and other aren’t, and that we ought to ask why this is.
For almost all of human history, almost everybody lived in what we’d now call extreme poverty. Many lived in tribes which didn’t really have anything we’d call an economic system. However, there were also large civilizations that existed for thousands of years without becoming prosperous, such as China and the Middle East. Few people really understand why this is.
In those civilizations, before modern times, there was no legal framework for allowing people to build up their wealth. Rulers understood that people had to earn their survival, and usually allowed that much. (But sometimes not even that much.) If someone started earning more than survival level, nothing stopped the Emperor/King/Sultan/Duke/etc… from stealing the excess wealth, and that’s generally what happened. Since ordinary people wouldn’t benefit from earning wealth, they generally didn’t even try to do so.
One day a new nation was founded, coincidentally in the same year that Adam Smith published his book. It was called the United State of America. It put most of Smith’s economic ideas into practice. Though it started out around the same level of prosperity as everyone else, the USA became the wealthiest nation in the history of the world by 1900. Then it got richer still, and at its peak had more wealth than the rest of the world combined. So understanding why the USA did so well compared to everyone else would seem to be a good idea.
One explanation that gets offered–in this thread, for instance–suggested that the USA succeeded because we had so much land and natural resources. Those help, to be sure, but many other nations with land and natural resources have been economic failures. (Russia, for instance.) By the late 19th and 20th centuries the USA not only grew more food than anyone else, but grew a lot more food per acre than anyone else. Why is that?
A farmer in 19th century Russia or most European countries had little financial motivation to improve his farm. Even if his income couldn’t be outright stolen, regulation and restrictions and taxes made it hard for him to make much profit.
By contrast, a farmer in the USA could grow as much as he was able and sell it when and where he chose, losing little or nothing to taxes. Consequently he had a strong financial motivation to grow more and improve his farm. This included using new technologies, and soon the USA produced new machinery to plow, sow, irrigate, reap, store and transport food more efficiently. Because farmers wanted to produce more, companies arose to help them do so.
Obviously this logic applied not only to farmers, but to everyone. In the early 19th century, progress in science and technology came mostly from Europe. Soon the USA overtook Europe and has stayed on top ever since. The majority of inventions that support the modern lifestyle, from the tractor to the electric grid to the airplane to the moving assembly line to the microchip, were made by Americans seeking profit. The fact that Americans were, until recently, allowed to make whatever goods they wanted, move those goods to wherever they wanted, and buy and sell goods at whatever prices they wanted gave them a financial motivation to work as hard as possible, invent new technologies and methods, and rapidly adopt what other people invented.
There must be a reason why the USA achieved so much prosperity so quickly, while no other nation did so. Economic freedom looks like a good candidate to be the main reason.
