People tend to use money in order to represent value. This is why Gross Domestic Product (GDP) has been the metric used to measure the success of nations since the early 1900s, and also why we tend to spend so much time worrying about how much money we have. But a monetary definition of “value” does not capture the many other factors in well-being.
