Production becomes social, but appropriation remains private. The social means of production remain the private property of a few. The general framework of formally recognised free competition remains, and the yoke of a few monopolists on the rest of the population becomes a hundred times heavier, more burdensome and intolerable.

Not only the general European, but the world proletarian revolution is maturing before the eyes of all, and it has been assisted, accelerated and supported by the victory of the proletariat in Russia. All this is not enough for the complete victory of socialism, you say? Of course it is not enough. One country alone cannot do more. But this one country, thanks to Soviet government, has done so much that even if Soviet government in Russia were to be crushed by world imperialism tomorrow, as a result, let us say, of an agreement between German and Anglo-French imperialism—even granted that very worst possibility—it would still be found that Bolshevik tactics have brought enormous benefit to socialism and have assisted the growth of the invincible world revolution.

Vladimir Lenin
The Proletarian Revolution and the Renegade Kautsky

It is said that life consists in constant growth and development and that is true: social life is not something immutable and static, it never remains at one level, it is in eternal motion, in an eternal pro-cess of destruction and creation. It was with good reason that Marx said that eternal motion and eternal destruction and creation are the essence of life. Therefore, life always contains the new and the old, the growing and the dying, revolution and reaction-in it something is always dying and at the same time something is always being born.
