 How to read Marx’s economic writings, and especially his masterpiece Capital Volume 1,  remains a matter of controversy. An orthodox reading is that Marx’s essential task is to contribute to economic theory, based on a modified form of the labour theory of value. Others warn against such a narrow interpretation, pointing out that the character of Marx’s writing and presentation is very far from what one would expect in a standard economic text. Hence William Clare Roberts (2017), for example, argues that Capital Volume 1 is fundamentally a work of political theory, rather than economics. Be that as it may, nevertheless, the work does contain substantial presentation of an economic analysis of capitalism, and it is on this that we will focus here.
