I had to do this compulsory course ECONOMICS 101 as part of my politics major. . I don't remember much of it but I do recall listening bored shatless on the history of monetary systems. They were from shells apparently, an extension of trade networks. . when he went into micro and macro economics was about the time I switched off completely. I think this chap is right to say what they
teach about money and what happens in the real world are completely different.
