Stalin: The imperialist bourgeoisie systematically bribed the upper stratum of skilled workers, the so-called labour aristocracy, by means of higher wages and other sops, using for this purpose part of the profits it derived from the colonies, from the exploitation of backward countries. This section of workers had produced quite a number of trade union and cooperative leaders, members of municipal and parliamentary bodies, journalists and functionaries of Social-Democratic organizations. When the war broke out, these people, fearing to lose their positions, became foes of revolution and most zealous defenders of their own bourgeoisies, of their own imperialist governments. https://wordsmith.social/protestation/quotes#quote2532
