(the article still had some of my text in re its distinguishing characteristics last I checked), had been given an earlier personal position vis. a vis (where my main contribution is at the start of the back matter, "Length and Semantics" thread in the index) more than a decade ago in the then current en wiki user home page. Here I'm updating for the intervening learning and the period going forward.
The essential distinction between the concept to be articulated and actually existing Capitalism, is that the latter is based on the exploitation of externalized and dead labour. Specifically, finance Capitalism, uses the dead form of labor value in money (whose ultimate source of value is the labor used in the production process that creates use value whose end products the finance Capitalists sell at a markup called "profit") controls production and thru it society. The hallmark of this distinction is that the finance Capitalist is virtually never the actual creator of the wealth she appropriates, but is at most a manager or original conceiver of some line of production, at least insofar as industrial production is concerned, petty bourgeois professionals, actors, athletes, etc. being a primitive form of the living kind to the extent they remain sole producers and don't use the dead form of thier own labor to enter the regular domain of conventional capitals in various ways.
Living Capitalism then would realize the earlier referred to synthesis of Randian Capitalism and various Socialisms. The essential distinction is that while finance Capitalism is based on the accumulation of the money form of value, from which it projects power, living Capitalism on the other hand is based on the accumulation of labor power itself, specifically that which produces intellectual property, for a similar purpose.
