Lenin: The proletariat does not cease the class struggle after it has captured political power, but continues it until classes are abolished -- of course, under different circumstances, in different form and by different means. And what does the "abolition of classes” mean? All those who call themselves socialists recognise this as the ultimate goal of socialism, but by no means all give thought to its significance. Classes are large groups of people differing from each other by the place they occupy in a historically determined system of social production, by their relation (in most cases fixed and formulated in law) to the means of production, by their role in the social organisation of labour, and, consequently, by the dimensions of the share of social wealth of which they dispose and the mode of acquiring it. Classes are groups of people one of which can appropriate the labour of another owing to the different places they occupy in a definite system of social economy. Clearly, in order to abolish classes completely, it is not enough to overthrow the exploiters, the landowners and capitalists, not enough to abolish their rights of ownership; it is necessary also to abolish all private ownership of the means of production, it is necessary to abolish the distinction between town and country, as well as the distinction between manual workers and brain workers. This requires a very long period of time. In order to achieve this an enormous step forward must be taken in developing the productive forces; it is necessary to overcome the resistance (frequently passive, which is particularly stubborn and particularly difficult to overcome) of the numerous survivals of small-scale production; it is necessary to overcome the enormous force of habit and conservatism which are connected with these survivals. https://wordsmith.social/protestation/quotes#quote9415
