Friedrich Engels: The individual capitalist is involved in struggle with all the other capitalists; the individual worker with all the other workers; all capitalists fight against the workers just as the mass of workers in their turn have, of necessity, to fight against the mass of capitalists. In this war of all against all, in this general confusion and mutual exploitation, the essence of present-day bourgeois society is to be found. https://wordsmith.social/protestation/quotes#quote4898
