Greenspan’s “progression” has been Randrhoid, apostate Randrhoid, neo-classical Keynesian and now he’s just confused and can’t decide which failed economic theory to espouse. Keynes was a contemporary of Douglas and Keynesianism was basically watered down, half @ssed plagiarized abstract Douglas that remained unconscious of the on the ground realities of the costing/pricing system ruled by the enforced conventions of cost accounting. Hence it allowed the monopoly, money creating business model of Finance to rule every other business model and 99% of the general populace.

Every current economic theory is way more complex and abstract than it needs to be because they have missed the micro-economic cost accounting reality that rules every enterprise and is hence a macro-economic reality as well.
