A common misunderstanding, this. Economists in theory don’t focus on starting with the right set of assumptions, like any gentleman they instead focus on starting with the right set of conclusions. They then, in theory, argue passive-aggressively over why their model is The Right One using increasingly obtuse game theoretic models, usually with a drawing of two lines intersecting. The rest of the world? We simply shrug and ignore them.
Much like the the people ignored the idiot savants tucked away in medieval monasteries. At some point they become useful, like when the king needs to know what the nature of God is, who It approves and why it’s him and not the other guy.
Now that we've traded our warrior nobility for economic nobility, the neurodivergent and mildly touched ones are tucked away in academia instead. Pleasantly seperated from their subject of study. To figure out the nature of "The Market", and why it is, in theory, as Rational and Self Organizing as a medieval Thomist Universe.
And we are like the medieval peasantry who cannot understand an iota of what they're scribbling in their intimidating books. But we can see they're still fighting over It, just like they fought over resolving the philosophic contradictions of the faith.
It makes one wonder: what shape and mission will They have next? Will it be in explaining the actions of some sentient supercomputer, which both feeds and spanks us? Or which irradiated plants will take us beyond the Seventh Sphere, in theory? More at eight.
