By stating that the analysis of the laws of motion governing the capitalist mode of production necessarily includes at least some essential elements … - Ernest Mandel

Not only have material wealth and the possibilities for freeing mankind definitively from the burden of meaningless, repetitive and mechanical work increased, but so too has the polarization of society between fewer and fewer owners of capital and more and more workers of hand and brain, forced to sell their labour-power to these owners. The concentration of wealth and power in a small number of giant industrial and financial corporations has brought with it an increasingly universal struggle between Capital and Labour.

Capital, explaining the origins of the capitalist mode of production, points towards the inevitable historical decline and fall of this same social system. An economic theory based upon the historical relativity of every economic system, its strict limitation in time, tactlessly reminds Messrs the capitalists, their hangers-on and their apologists that capitalism itself is a product of history. It will perish in due course as it once was born. A new social form of economic organization will then take the place of the capitalist one: it will function according to other laws than those which govern the capitalist economy.

For Marx, ‘pure’ economic theory, that is economic theory which abstracts from a specific , is impossible.
