It's all dawned on me - finally!
Till Marshall, there was NO discipline called "economics". It was only political economy. That is because the study of government (evil, etc.) was an INTEGRAL part of the study of the economy. One could not talk about the economy without spending much time to understand the origin of, and limitations of government intervention.
But from Alfred Marshall onwards, the government was ASSUMED to be perfect (superior to God). Any questions about the government's origin and capability were now brushed under the carpet, tucked into a couple of nondescript lines or into footnotes. Government was BANISHED from economics because it was the PERFECT ENFORCER OF EFFICIENCY.
In my view, any economist who doesn't spend MORE TIME to understand the government than he does to understand trivial maths (economists undertake the most trivial of all maths), is a pseudo-economist. Such people are the first to support TERRORISM such as lockdowns, vaccine mandates, mask mandates and mandatory fortification. Their STUPID, trivial "equations" tell them so!
