Human beings are so made that the ones who do the crushing feel nothing; it is the person crushed who feels what is happening. Unless one has placed oneself on the side of the oppressed, to feel with them, one cannot understand.
What is surprising is not that oppression should make its appearance only after higher forms of economy have been reached, but that it should always accompany them.
The whole evolution of present-day society tends to develop the various forms of bureaucratic oppression and to give them a sort of autonomy in regard to capitalism as such.
