In a world of strangers … a new sucker arrives every minute … The dealings of strangers are subject to social norms. In a world of Hobbesian asocial nomads the next stranger you meet would just as well shoot you as shake your hand. That is why the airlines are crowded with business travellers, on their way to making friends (McCloskey, 1994, p. 373).
