 By the same token, most egalitarians do not advocate an equality of outcome, but different kinds of equality of opportunity, due to their emphasis on a pair of morally central points: that individuals are responsible for their decisions, and that the only things to be considered objects of equality are those which serve the real interests of individuals. The opportunities to be equalized between people can be opportunities for well-being (i.e. objective welfare), or for preference satisfaction (i.e., subjective welfare), or for resources. It is not equality of objective or subjective well-being or resources themselves that should be equalized, but an equal opportunity to gain the well-being or resources one aspires to. Such equality depends on their being a realm of options for each individual equal to the options enjoyed by all other persons, in the sense of the same prospects for fulfillment of preferences or the possession of resources. The opportunity must consist of possibilities one can really take advantage of. Equal opportunity prevails when human beings effectively enjoy equal realms of possibility.
