"When parents warn their children that the world is full of selfish people who want to take advantage of them and who will treat them unfairly, they do the same thing as warning them that there are other people in the world like the parents themselves. It is tantamount to informing them that, even with a world full of people like that, exploitative and unjust, and even with life being very difficult, the parents (who knew all this) forced their children into being, even though it was avoidable."
