Very novice understanding of economics: The circle of economics begins with demand and spending, spending moves supply around and banks get deposits while investors speculate on stock prices and the fed tries to keep inflation down with low interest rates. Somehow the people are mostly employed and advertisers help you get motivated to put more money into the loop, everyone wants a house and a car and some want to appear rich on social media! This map is not one of pillars, but has underlying greed and social status disorders. It doesn't have a real foundation. Yet there it is, beautiful.
