The ruthless unity in the culture industry is evidence of what will happen in politics. Marked differentiations such as those of A and B films, or of stories in magazines in different price ranges, depend not so much on subject matter as on classifying, organising, and labelling consumers. Something is provided for all so that none may escape; the distinctions are emphasised and extended. The public is catered for with a hierarchical range of mass-produced products of varying quality, thus advancing the rule of complete quantification. Everybody must behave (as if spontaneously) in accordance with his previously determined and indexed level, and choose the category of mass product turned out for his type. Consumers appear as statistics on research organisation charts, and are divided by income groups into red, green, and blue areas; the technique is that used for any type of propaganda.
