The listed theories below are some of the most prominent theories within the field. With this in mind, the list is in no way to be considered exhaustive for distributive justice theory.
Justice as fairness In his book
A Theory of Justice, John Rawls outlines his famous theory about justice as fairness. The theory consists of three core components: • the equality of people in rights and liberties; • the equality of opportunities for all; and • an arrangement of economic inequalities focused on benefit maximisation for those who are least advantaged.
The just 'basic structure' Building a modern view on
social contract theory, Rawls bases his work on an idea of justice being rooted in the
basic structure, constituting the fundamental rules in society, which shape the social and economic institutions, as well as the governance. This basic structure is what shapes the citizens' life opportunities. According to Rawls, the structure is based on principles about
basic rights and duties that any self-interested, rational individual would accept in order to further his/her own interests in a context of social cooperation. In his envisioning of the original position, it is created from a judgement made through negotiations between a group of people who will decide on what a just distribution of primary goods is (according to Rawls, the primary goods include freedoms, opportunities, and control over resources). These people are assumed to be guided by self-interest, while also having a basic idea of morality and justice, and thus capable of understanding and evaluating a moral argument. Thereby, such veil creates an environment for negotiations where the evaluation of the distribution of goods is based on general considerations, regardless of place in society, rather than biased considerations based on personal gains for specific citizen positions. With this in mind, Rawls theorizes two basic
principles of just distribution. The first principle, the
liberty principle, is the equal access to basic rights and liberties for all. With this, each person should be able to access the most extensive set of liberties that is compatible with similar schemes of access by other citizens. Thereby, it is not only a question of positive individual access but also of negative restrictions so as to respect others' basic rights and liberties. This idea of utilisation maximisation, while being a much broader philosophical consideration, also translates into a theory of justice.
Conceptualising welfare While the basic notion that utilitarianism builds on seems simple, one major dispute within the school of utilitarianism revolved around the conceptualisation and measurement of
welfare. Opposite this, another path focuses on a subjective evaluation of happiness and satisfaction in human lives.
Egalitarianism Based on a fundamental notion of equal worth and moral status of human beings, egalitarianism is concerned with equal treatment of all citizens in both respect and in concern, and in relation to the state as well as one another. Egalitarianism focuses more on the process through which distribution takes place, egalitarianism evaluates the justification for a certain distribution based on how the society and its institutions have been shaped, rather than what the outcome is. The main issue with egalitarian conceptions of distributive justice is the question concerning what kind of equality should be pursued. This is because one kind of equality might imply or require inequality of another kind. Strict egalitarianism, for instance, requires the equal allocation of material resources to every person of a given society. The principle of strict equality therefore holds that even if an unequal distribution would make everyone better off, or if an unequal distribution would make some better off but no one worse off, the strictly egalitarian distribution should be upheld. This notion of distributive justice can be critiqued because it can result in Pareto suboptimal distributions. Thus, the Pareto norm suggests that principles of distributive justice should result in allocations in which it is no longer possible to make anyone better off without making anyone else worse off. This illustrates a concern for the equality of welfare, which is an ex post conception of equality as it is concerned with the equality in outcomes. This conception has been critiqued by those in favour of ex ante equality, that is equality in people´s prospects, which is captured by alternative conceptions of equality such as those that demand equality of opportunity. In
Marxism-Leninism according to
Vladimir Lenin the slogan "
He who does not work, neither shall he eat" is a necessary approach to distributive justice on the path towards a
communist society. == Application and outcomes ==
