In other words, we should level the playing field on which competition for superior positions in the social hierarchy will eventually take place. The playing field is leveled when unchosen circumstances of individuals are equalized, so that individuals can reasonably be held responsible for their choices that determine their eventual places in the social hierarchy. One might picture level-playing-field (LPF) equality of opportunity as operating in the sphere of education and socialization and health care to prepare young people for adult status when responsible agency in a field of social competitions will be expressed. Opportunities are equalized when unchosen circumstances including native talents are counterbalanced so that nothing but the quality of people's choices (to the degree they can reasonably be held responsible for them) and their foreseeable effects determines their fate in social competitions. The effects of unchosen luck are to be eliminated.
