 The foregoing is relatively uncontroversial, but what made Rawls’ (and Barry’s) arguments so interesting was their claim that this line of reasoning actually leads to much stronger (and more contentious) requirements for social justice. They note that even with formal equality of opportunity, there will remain many factors over which people have no control but which will affect their lifetime economic prospects, such as whether a person’s family can afford to purchase good quality educational opportunities or health care. A society therefore will have reasons to adopt a more substantial equality of opportunity principle, with equal opportunities for education, health care, etc.—the same reasons it had for adopting a merely formal equality of opportunity principle.
