Money Money Money - Makes the World go Round (Liza Minelli in "Cabaret")
Using our money as a tool for buying products and services is paying for what is already made, paying off the past. When we save or invest via banks or crowdfunding we are financing the production of goods and services in-the-making. And when paying for schools or science and research (direct or via taxes) we are financing the producers and the products of the future and especially all future innovations! So when we look to money in the sequence of time we can choose to use our money for products and services of yesterday today or tomorrow!
The easiest way to understand how money makes the world go round is to look to the reality first and then look to the money as a kind of mirror or bookkeeping of that reality. Because money is nothing more than a way of making visible what happens in the real world of the economy. It helps us to understand economy also when studying the most complex issues about creation of money or alternative local or global currencies, use or misuse of money as an instrument, and about measuring the value or quality of products and services.
While division of labour and all creation of wealth is an economic process of production, trade and consumption, division of that wealth however is not an economic but a legal question. While economy is the science of products and services, income and (in)equality is all about people!
