Quick Answer
Equality of opportunity is the principle that positions and advantages in society should be open to all on the basis of merit, not on the basis of arbitrary factors such as race, gender, or family background. Formal equality of opportunity requires that legal barriers to competition be removed. Substantive or fair equality of opportunity, as developed by John Rawls, requires that individuals with similar talents and motivation have similar chances of success, regardless of their social background.
Key Takeaways
- ✦Formal equality of opportunity removes legal barriers to competition.
- ✦Substantive equality of opportunity requires fair access regardless of social background.
- ✦Rawls' fair equality of opportunity is a central formulation of the principle.
- ✦Critics argue that equality of opportunity is insufficient without addressing outcome inequality.
What Is Equality of Opportunity?
Equality of opportunity is a normative principle that holds that positions of advantage in society should be open to all on the basis of fair competition, not on the basis of arbitrary characteristics such as race, gender, ethnicity, or family background. It is a central ideal of liberal societies and a key concept in debates about social justice, education policy, and economic fairness.
Formal Equality of Opportunity
The simplest version of the principle is formal equality of opportunity, which requires that legal barriers to competition be removed. This means that formal discrimination on the basis of race, gender, or religion is prohibited, and that positions are awarded on the basis of relevant qualifications. Milton Friedman (1912-2006) defended this conception, arguing that free markets naturally promote equality of opportunity by rewarding talent and effort.
Fair Equality of Opportunity
John Rawls (1921-2002) argued that formal equality of opportunity is insufficient. In A Theory of Justice, he proposed a principle of fair equality of opportunity, which requires that those with similar talents and motivation have similar chances of success, regardless of their social class of origin. This principle goes beyond the removal of formal barriers to require positive measures to ensure that children from disadvantaged backgrounds have access to quality education, healthcare, and other resources.
The Capabilities Approach
Amartya Sen (born 1933) and Martha Nussbaum (born 1947) have criticized the focus on opportunity as too narrow. They argue that what matters is not merely having opportunities but having the genuine capability to take advantage of them. Nussbaum's capabilities approach identifies a list of central capabilities that every society should secure for all citizens.
The Libertarian Critique
Robert Nozick (1938-2002) argued that government efforts to enforce equality of opportunity violate individual property rights. In Anarchy, State, and Utopia, he contended that the only legitimate role of the state is to protect negative rights, not to promote equality of opportunity.
Equality of Opportunity vs. Equality of Outcome
A key debate concerns whether equality of opportunity is sufficient or whether equality of outcome is also necessary. Defenders of equality of opportunity argue that as long as the competition is fair, unequal outcomes are justified by differences in talent and effort. Critics argue that genuine equality of opportunity is impossible without addressing the structural inequalities that shape outcomes.
Conclusion
Equality of opportunity remains a powerful but contested ideal. While nearly everyone endorses it in some form, there is deep disagreement about what it requires in practice and whether it is sufficient for a just society.
