To decide once every few years which members of the ruling class is to repress and crush the people through parliament — this is the real essence of … - Vladimir Lenin

When we are reproached with having established a dictatorship of one party and, as you have heard, a united socialist front is proposed, we say, "Yes, it is a dictatorship of one party! This is what we stand for and we shall not shift from that position because it is the party that has won, in the course of decades, the position of vanguard of the entire factory and industrial proletariat. This party had won that position even before the revolution of 1905. It is the party that was at the head of the workers in 1905 and which since then — even at the time of the reaction after 1905 when the working-class movement was rehabilitated with such difficulty under the Stolypin Duma — merged with the working class and it alone could lead that class to a profound, fundamental change in the old society.

A monopoly, once it is formed and controls thousands of millions, inevitably penetrates into every sphere of public life, regardless of the form of government and all other "details".

When we say that experience and reason prove that men are not equal, we mean by equality, equality in abilities or similarity in physical strength and mental ability.
It goes without saying that in this respect men are not equal. No sensible person and no socialist forgets this. But this kind of equality has nothing whatever to do with socialism.
