In the last 200 years the exploitation of envy, its mobilization among the masses, coupled with the denigration of individuals, but more frequently of classes, races, nations or religious communities has been the very key to political success. The history of the Western World since the end of the eighteenth century cannot be written without this fact constantly in mind. All leftist “isms” harp on this theme, i.e., on the privilege of groups, minority groups, to be sure, who are objects of envy and at the same time subjects of intellectual-moral inferiorities. They have no right to their exalted positions. They ought to conform to the rest, become identical with “the people,” renounce their privileges, conform. If they speak another language, they ought to drop it and talk the lingo of the majority. If they are wealthy their riches should be taxed away or confiscated. If they adhere to an unpopular ideology, they ought to forget it. Everything special, everything esoteric and not easily understood by the many becomes suspect and evil (as for instance the increasingly “undemocratic” modern art and poetry).
