“ If I were asked to name the deadliest subversive force within capitalism--the single greatest source of its waning morality--I should without hesitation name advertising. How else should one identify a force that debases language, drains thought, and undoes dignity? If the barrage of advertising, unchanged in its tone and texture, were devoted to some other purpose--say the exaltation of the public sector--it would be recognized in a moment for the corrosive element that it is. But as the voice of the private sector it escapes this startled notice. I mention it only to point out that a deep source of moral decay for capitalism arises from its own doings, not from that of its governing institutions. ”
