Official science tried, by a conspiracy of silence, to kill the works of Marx, who by a theoretical and historical analysis of capitalism had proved that free competition gives rise to the concentration of production, which, in turn, at a certain stage of development, leads to monopoly.
When the workers of a single factory or of a single branch of industry engage in struggle against their employer or employers, is this class struggle? No, this is only a weak embryo of it. The struggle of the workers becomes a class struggle only when all the foremost representatives of the entire working class of the whole country are conscious of themselves as a single working class and launch a struggle that is directed, not against individual employers, but against the entire class of capitalists and against the government that supports that class. Only when the individual worker realizes that he is a member of the entire working class, only when he recognises the fact that his petty day-to-day struggle against individual employers and individual government officials is a struggle against the entire bourgeoisie and the entire government, does his struggle become a class struggle.
