But who, in the Western world, has not been deranged by a toxic cocktail of dissatisfaction, restlessness, desire and resentment? Who has not yearned to be younger, richer, more talented, more respected, more celebrated, and, above all, more sexually attractive?

It is possible that a starving African farmer has less sense of injustice than a middle-aged Western male who has never been fellated.
