"Much of what is today called "social criticism" consists of members of the upper classes denouncing the tastes of the lower classes (bawdy entertainment, fast food, plentiful consumer goods) while considering themselves egalitarians."

The ideas of the ruling class are in every epoch the ruling ideas, i.e. the class which is the ruling material force of society, is at the same time its ruling intellectual force. The class which has the means of material production at its disposal, has control at the same time over the means of mental production, so that thereby, generally speaking, the ideas of those who lack the means of mental production are subject to it. The ruling ideas are nothing more than the ideal expression of the dominant material relationships, the dominant material relationships grasped as ideas.
