It's about becoming the oppressor.
[T]he first step in the revolution by the working class is to raise the proletariat to the position of ruling class to win the battle of democracy.So by turning the tables in a class war, it can abolish a class war? Not how it works. But by advocating despotic inroads, Marx admits that the only goal is for the proletariat to become the oppressor.
The proletariat will use its political supremacy to wrest, by degree, all capital from the bourgeoisie, to centralize all instruments of production in the hands of the State, i.e., of the proletariat organized as the ruling class; and to increase the total productive forces as rapidly as possible.
Of course, in the beginning, this cannot be effected except by means of despotic inroads on the rights of property, and on the conditions of bourgeois production; by means of measures, therefore, which appear economically insufficient and untenable, but which, in the course of the movement, outstrip themselves, necessitate further inroads upon the old social order, and are unavoidable as a means of entirely revolutionizing the mode of production. [ ]
If the proletariat during its contest with the bourgeoisie is compelled, by the force of circumstances, to organize itself as a classif, by means of a revolution, it makes itself the ruling class, and, as such, sweeps away by force the old conditions of productionthen it will, along with these conditions, have swept away the conditions for the existence of class antagonisms and of classes generally, and will thereby have abolished its own supremacy as a class.
Well said.
