The capitalist mode of production and accumulation, and therefore capitalist private property, have for their fundamental condition the annihilation of self - earned private property: in other words, the expropriation of the labourer.

Capital is reckless of the health or length of life of the laborer, unless under compulsion from society.

In its struggle for power the proletariat has no other weapon but organisation. Disunited by the rule of anarchic competition in the bourgeois world, ground down by forced labour for capital, constantly thrust back to the 'lower depths' of utter destitution, savagery, and degeneration, the proletariat can, and inevitably will become an invincible force only through its ideological unification on the principles of Marxism being reinforced by the material unity of organisation, which welds millions of toilers into an army of the working class.

Capitalism is commodity production at the highest stage of development, when labor power itself becomes a commodity. The growth of internal exchange, and particularly of international exchange, is a special feature of capitalism. The uneven and spasmodic character of the development of individual enterprises, of individual branches of industry and individual countries, is inevitable under the capitalist system.

He who before was the money owner, now strides in front as capitalist; the possessor of labor-power follows as his laborer. The one with an air of importance, smirking, intent on business; the other hesitant, like one who is bringing his own hide to market and has nothing to expect but a hiding.

It appears then, that capitalist production comprises conditions independent of good or bad will, conditions which permit the working-class to enjoy that relative prosperity only momentarily, and at that always only as the harbinger of a coming crisis.
