of price, and commodity value. (this caused some of his readers to think wrongly that use-value played no role in his theory). "The utility makes it a use value," The neoclassicals, on the other hand, typically see prices as the quantitative expression of the general utility of products for buyers and sellers, instead of expressing their exchange-value. For "Price is the money-name of the labour realised in a commodity". In neoclassical economics, this utility is ultimately subjectively determined by the buyer of a good, and not objectively by the intrinsic characteristics of the good. Thus, neoclassical economists often talk about the marginal utility of a product, i.e., how its utility fluctuates according to consumption patterns. This kind of utility is a "general utility" which exists independently from particular uses that can be made of a product, the assumption being that if somebody wants, demands, desires or needs a good, then it has this general utility. According to his supporters Marx would have allegedly rejected the concept of marginal utility precisely because it accentuated profit on capital returns over the usefulness or utility of labour. Thus the wider application of general utility lay in variable rates of productivity, since higher labour inputs could raise or lower the price of commodity. This was the true concept of Use as a Value system: the higher the rate of 'productiveness' the more labour 'crystallised' in the article. Marx rejects any economic doctrine of consumer sovereignty, stating among other things in his first chapter to Das Kapital that "In bourgeois societies the economic fictio juris prevails, that every one, as a buyer, possesses an encyclopaedic knowledge of commodities". In summary, different concepts of use value lead to different interpretations and explanations of trade, commerce and capitalism. Marx's main argument is that if we focus only on the general utility of a commodity, we abstract from and ignore precisely the specific social relations of production which created it. "Indifference" of capitalists Some academics such as Professor Robert Albritton, a Canadian political scientist, have claimed that according to Marx, capitalists are basically "indifferent" to the use-value of the goods and services in which they trade, since what matters to capitalists is just the money they make; whatever the buyer does with the goods and services produced is, so it seems, of no real concern. But this is arguably a misunderstanding of business activity and the bourgeoisie as
