[w]e too have worked with a concept that puts capitalist development first, and workers second. This is a mistake. And now we have to turn the problem on its head, reverse the polarity, and start again from the beginning: and the beginning is the class struggle of the working class. (from Lenin in England 1964).
There are two conditions for the centrality of the working class to function politically. The first necessity is that factory workers are surrounded by a large penumbra of social consensus, the second that their effect on the political and their relationship to institutions remains stable over a long period. It must be made evident and perceptible, with practical actions, that this state must be simultaneously defended and changed. What must be defended are the formal guarantees, the constitutional mechanisms of equilibrium and the significance of the political agreement between the democratic parties. What has to be changed is the significance of power, the functioning of the decision-making mechanisms, the guidance of the economy, and the control, consumption and application of social wealth.
