  Further issues may be raised about the nature of the individuals among whom equality should obtain. One might hold that across whatever kind of group is deemed to be the relevant domain of equality, individuals in the domain should be made equal in condition over the course of their lives. This view would allow that people might fare unequally well at different stages of life so long as their lifetimes taken as a whole are identical in faring well. Another possibility is that the individual persons at the same stage of the life cycle should be rendered equal in condition. On this latter view, a society in which over time the people who are old all enjoy the same condition, and likewise the people who are young and those who are middle-aged, could perfectly conform to the ideal of stage-by-stage equality of condition even if the old are (say) far better off than the middle-aged and the middle-aged are always far better off than the young. From the whole-lives perspective, stage-by-stage equality is unacceptable, because some people die young, and those who die young never get to enjoy the peak condition. One might uphold a stringent view that requires, so far as possible, that all achieve the same lifetime level of good and that in addition at each separate stage of life (individuated how?) everyone achieves the same level of good. Another possible view is that equality should be formulated so it demands that from now, the condition of all those living should be equalized (regardless of what condition people enjoyed in the past).
