“Competition, in other words, does not determine the ‘content’ of the laws of economics, but it does provide the pressures that constrain economic subjects (capitalists, workers, landlords, consumers, etc.) to act in ways that conform to these laws. Marx’s view was basically the same, though he expressed it differently. The following passages from the ‘Grundrisse’ are representative of his comments on competition: “Competition generally, this essential locomotive force of the bourgeois economy, does not establish its laws, but is rather their executor. Unlimited competition is therefore not the presupposition for the truth of the economic laws, but rather the consequence  – the form of appearance in which their necessity realizes itself…competition therefore does not ‘explain’ these laws; rather, it lets them be ‘seen’, but does not produce them”. (Martin Nicolaus, trans. [New York: Vintage, 1973], p. 552)” [Paul M. Sweezy, Four Lectures on Marxism. Dialectics and Metaphysics, 1981]
