First come technical tools, machines. Here again applies the law that struggle leads to perfection. The machine that is more improved outstrips the less improved, the machines that cannot perform much, and the simple tools are exterminated and machine technique develops with gigantic strides to ever greater productivity. This is the real application of Darwinism to human society. The particular thing about it is that under capitalism there is private property, and behind every machine there is a man. Behind the gigantic machine there is a big capitalist and behind the small machine there is a small capitalist. With the defeat of the small machine, the small capitalist, as capitalist, perishes with all his hopes and happiness. At the same time the struggle is a race of capital. Large capital is better equipped; large capital is getting ever larger. This concentration of capital undermines capital itself, for it diminishes the bourgeoisie whose interest it is to maintain capitalism, and it increases that mass which seeks to abolish it. In this development, one of the characteristics of capitalism is gradually abolished. In the world where each struggles against all and all against each, a new association develops among the working class, the class organization. The working class organizations start with ending the competition existing between workers and combine their separate powers into one great power in their struggle with the outside world. Everything that applies to social groups also applies to this class organization, brought about by natural conditions. In the ranks of this class organization, social motives, moral feelings, self-sacrifice and devotion for the entire body develop in a most splendid way. This solid organization gives to the working class that great strength which it needs in order to conquer the capitalist class. The class struggle which is not a struggle with tools but for the possession of tools, a struggle for the right to direct industry, will be determined by the strength of the class organization. Let us now look at the future system of production as carried on under Socialism. The struggle leading to the perfection of the tools does not cease. As before under capitalism, the inferior machine will be outdistanced and brushed aside by the one that is superior. As before, this process will lead to greater productivity of labor. But private property having been abolished, there will no longer be a man behind each machine calling it his own and sharing its fate. Machines will be common property, and the displacement of the less developed by the better developed machinery will be carried out upon careful consideration.
