Mary: You were well trained in the economics of Lionel Robbins. What is maximized may be religious experience, or the constraint may be moral precept; so goals and constraints may not be material or materialistic; but to practice Economics, as opposed to Sociology, Psychology, or Political Science, these things are dealt with in terms of the complement of mateiral means that is used or produced, or, indeed, not used, or potentially produced, in the constrained maximizing process. Knowledge is not material, but economists treat it from the point of view of its cost and/or productivity, measured in labour-time, socially necessary labour, relative scarcity, abstinence, and the like, in the economics of Lionel Robbins and some other economicses. Maximizing process is tautological, an it is one kind of economics that sees the world from that point of view. Schumpeterian economics sees the sorld from the point of view of creative destruction of constraints. No doubt, the maximizing process is present, but that is not the focus in Schumpeterian economics; and since neoclassical economics deals with maximization WITHIN constraints, Schumpeterian economics is outside the modus operandi of neolassical economics.
