Sorry to say, but your observation is wrong. They do make explicit statements about the utility of enjoying the arts: > They each expect to experience €6,000,000 worth of individual utility from enjoying the additional €9,000,000 of art. > Net social welfare: > Total Utility = 3 × €6,000,000 = €18,000,000 ...just to go ahead and to deny any relevancy of the utility of saved lives: > the three contributors don’t experience that utility (other than feeling good about those lives being saved, but that’s not the kind of utility we’re trying to maximize).
