Here an excerpt from Lenin, “Imperialism, the Highest Stage of Capitalism”, dealing with the question of the labor aristocracy.

“It is precisely the parasitism and decay of capitalism, characteristic of its highest historical stage of development, i.e., imperialism.

As this pamphlet shows, capitalism has now singled out a handful (less than one-tenth of the inhabitants of the globe; less than one-fifth at a most “generous” and liberal calculation) of exceptionally rich and powerful states which plunder the whole world simply by “clipping coupons”.

Capital exports yield an income of eight to ten thousand million francs per annum, at pre-war prices and according to pre-war bourgeois statistics. Now, of course, they yield much more.

Obviously, out of such enormous superprofits (since they are obtained over and above the profits which capitalists squeeze out of the workers of their “own” country) it is possible to bribe the labour leaders and the upper stratum of the labour aristocracy.

And that is just what the capitalists of the “advanced” countries are doing: they are bribing them in a thousand different ways, direct and indirect, overt and covert.

This stratum of workers-turned-bourgeois, or the labour aristocracy, who are quite philistine in their mode of life, in the size of their earnings and in their entire outlook, is the principal prop of the Second International, and in our days, the principal social (not military) prop of the bourgeoisie.

For they are the real agents of the bourgeoisie in the working-class movement, the labour lieutenants of the capitalist class, real vehicles of reformism and chauvinism. In the civil war between the proletariat and the bourgeoisie they inevitably, and in no small numbers. take the side of the bourgeoisie, the “Versaillese” against the “Communards”.

Unless the economic roots of this phenomenon are understood and its political and social significance is appreciated, not a step can be taken toward the solution of the practical problem of the communist movement and of the impending social revolution.”
