Had a fairly random, albeit particularly interesting IMO, thought and felt like hoisting its flag out to see if it catches return fire. So here:
Consider the varying definitions used for “capitalism”. People use it to refer to everything from a system of inherent state-collusion in the favor of connected interests, to the anarcho-capitalist definition of an ideal open market order, to the simple (and simplistic) “anything involving prices”. These are about the process, but what about the root? That is, what about Capital? Economics textbooks routinely say that Capital is not — NOT! — a reference to money, but to basically Stuff that can be used to make other Stuff. Yet, significant portions of modern economic activity have pretty much jack squat to do with this anymore, to an extent where that textbook definition is alien to most: when you say “capital” to the general public, they generally respond “money”. The influence of finance looms large here.
This poses a dilemma with regard to that textbook definition: stick to it, and it is arguable that modern economies approach a post-capitalist state.
