Economics is all about money, right? It’s all about theories on how to distribute it, use it, make it, or protect it, yes? This is a common perception, and the focus on money dominates the area of political and personal understanding of all things related to important concepts like markets and wealth.
Yet there is substantial evidence that this is simply inadequate at best, wrong at worst. The purpose of money, according to a rigid definition, is to be a medium of exchange and a store of value. But there is quite a lot of evidence that as a store of value, a representation of accumulated wealth, it often fails horribly.
Money only works in a dynamic sense. There are several ways to read that statement, and they are all valid points.
