The three most promising theories of distributive ethics are presented: Utilitarianism, with or without a prioritarian amendment. The maximin/leximin theory. Egalitarianism. Utilitarianism urges us to maximize the sum-total of happiness. When prioritarianism is added to utilitarianism we are instead urged to maximize a weighted sum of happiness, where happiness weighs less the happier you are and unhappiness weighs more the more miserable you are. The maximin/leximin theory urges us to give absolute priority to those who are worst off. Egalitarianism gives us two goals: to maximize happiness but also to level out differences with regard to happiness between persons. All of these theories are justifiable. In abstract thought experiments they conflict. When applied in real life they converge in an unexpected manner: more resources should be directed to mental health and less to marginal life extension. It is doubtful if the desired change will take place, however. What gets in its way is human irrationality.
