" Every society rests on a barbarian base. The people who don't understand civilization, and wouldn't like it if they did. The hitchhikers. The people who create nothing, and who don't appreciate what others have created for them, and who think civilization is something that just exists and that all they need to do is enjoy what they can understand of it--luxuries, a high living standard, and easy work for high pay. Responsibilities? Phooey! What do they have a government for? "
