Capitalism is not synonymous with a free market, given that if the medium enabling markets is privately held, we are all tenant farmers to the banks.
As executive and regulatory function, government serves as the nervous system of society, while money and banking function as blood and the circulation system. We have evolved enough to understand that government as private enterprise doesn't work, given the vagaries of genetics and the loss of contact with the larger community. We have yet to realize the same principles apply to banking.
With public government and private banking, the banks rule, since they are subject to far less oversight, don't have to plan around election cycles and can control the finances of anyone presuming to run for office.
Given the one thing the banks really need from government is the debt to back their assets, it is no wonder that is the one job at which the flunkies allowed in office excel.
The secret sauce of capitalism is public debt backing private wealth.
As a medium, money functions as a social contract and network, but people assume it to be a commodity, so we try to extract and store it, while markets need it to circulate. Econ 101 refers to it as both medium of exchange and store of value, but these are different functions. Blood is a medium, fat is a store. So to store the asset side of the ledger, there has to be a debt to back it.
The reality is that we own money like we own the section of road we are using, or the air and water flowing through our bodies.
Eventually we will have to come to recognize that.
