" Now and then the workers are victorious, but only for a time. The real fruit of their battles lies not in the immediate result but in the ever improved means of communication that are created in modern industry and that place the workers of different localities in contact with one another. It was just this contact that was needed to centralize the numerous local struggles, all of the same character, into one national struggle between classes. But every class struggle is a political struggle. And that union, to attain which the burghers of the middle ages, with their miserable highways, required centuries, the modern proletarians, thanks to railways, achieve in a few years. "

― Karl Marx , The Communist Manifesto
