Caring relationships and material caregiving are politically significant goods that should be distributed according to principles of justice. I argue that, within Rawlsian liberalism, care should be considered a primary good and propose a third principle of justice requiring access to the social and legal supports of caring relationships. I examine what social and legal institutions supporting care might require, with particular attention to allowing the infirm elderly and persons with disabilities access to caring relationships. I propose the formation of a Care Corps, providing access to caring relationships for elderly and housebound citizens. If universally required and compensated, the Care Corps could address two other injustices related to care: the unjust distribution of caring labor between men and women and the relatively low status of caring work.
