Reports and discussions should be aimed at deciding whether the capitalist system still reigns—however much it may have modified itself—or whether industrial development has made the very concept of capitalism, the difference between capitalist and non-capitalist states, and the very critique of capitalism redundant. In other words, is the thesis that Marx is obsolete (a very widespread thesis in sociology) correct? According to this thesis, the world is so permeated by the previously undreamed-of development of technology that the social relation which once defined capitalism—the conversion of living work into goods, and the class separation which it brought about—has lost its relevance, if indeed it has not degenerated into a superstition. And here one may point to unmistakable signs of convergence between the most technically advanced countries, the United States and the Soviet Union. In the principal western countries class differences in living-standards and class consciousness are altogether far less in evidence than in the decades during and immediately after the industrial revolution. The prognoses of the class theory, such as the prediction of impoverishment and collapse, have not come true as drastically as they were meant to—as they must have been meant to, unless one is to deprive these predictions of most of their meaning. Even if Marx's by no means unambiguous law of falling profit rates had proved true, within the system, we should have had to concede that capitalism had discovered resources within itself which enabled the collapse to be relegated to the Greek kalends. There is no doubt that the immense increase in technological potential and the large amount of consumer goods available to all inhabitants of the highly industrialized countries are foremost among these resources. And at the same time the relations of production proved to be more elastic, in the face of this technological development, than Marx credited them with being.
