Economics is not about money but our collective household as human-beings. Economics means rules of the household (in ancient Greek), and I don’t know about you, but I don’t manage the performance of my household with money but by principle.
Money has lost most of its trust because money is not coupled to evolutionary merit. Hence the metric of money as a prognosticator of economic gameplay is as relevant as the report card of your child is an indication of their success in life.
That realization puts in a nail in classical economics and any derivatives thereof, including trickle-down or up economics.
