Werner Sombart,
Socialism and the Social Movement in the 19th Century
“ Thus the existence of capitalism is the necessary preliminary condition of the proletariat, and so of the modern social movement.But how stands it with the proletariat? What are the conditions under which the working-class lives? And how has it come to pass that out of these conditions those particular tendencies and demands have arisen which, as we shall find, have come out of this proletariat? Usually, when one is asked concerning the characteristics of the modern proletariat, the first answer is—the great misery in which the masses are sunk. ”
