Keynes had a good mind alright, but his analysis was incomplete both policy-wise and philosophically. His contemporary Douglas was one of the first to recognize the creditary nature of money, and being an engineer by profession (as well as a cost accountant and the modern equivalent of an efficiency expert) looked directly at commerce, its monetary empirical facts and then the mathematical implications of those datums. Starting from those engineering, scientific and calculus roots came policies that would have transformed modern economies. Keynes once referred to Douglas as a private, not a Major in economic reform (Douglas was referred to as Major Douglas). I’m afraid it was the other way around. There have only been three modern economic philosophers, Smith, Marx and Douglas.
In these three are the dialectic expressed:
Smith/Capitalism/Thesis
Marx/Socialism/Antithesis
Douglas/Social Credit/Synthesis
