If we accept these plausible assumptions, the following conclusion is difficult to escape: a consistent utilitarian cannot be impartial about persons, only about utility. Since some individuals generate far more utility than others, their interests must matter more. Thus, the supposed impartiality of utilitarianism collapses into a covert form of moral elitism. Persons are to be valued not as ends, but as instruments of aggregate utility. The famous actor, the brilliant musician, the genius doctor should be treated better than the ordinary farmer or the middling painter.
Very convincing
