“The real barrier of #capitalist production is #capital itself.” The passage comes from part three of the third volume of Capital, entitled “The Law of the Tendency of the Rate of Profit to Fall”. The subsequent sentences have some bearing on the MR analysis: “Capital and its self-expansion appear as the starting and the closing point, the motive and the purpose of production; that production is only production for capital and not vice versa, the means of production are not mere means for a constant expansion of the living process of the society of producers”-#Marx, 1972, p250.
