In 1776, Scottish economist
Adam Smith published
The Wealth of Nations. Smith argued that when businesses make more profits, they can expand their businesses, and therefore generate more wealth for everyone. This is the basic principle of capitalism. Of course, Smith assumed that people would use their profits to invest in society, not hoard the money for themselves. To
Harari, this idea of reinvesting profits and increasing productivity is a very modern idea. Harari thinks that capitalism began as a theory but it soon grew into an “ethic—a set of teachings about how people should behave, educate their children, and even think.” Harari sees capitalism as a “new religion.”
