A familiar conservative objection to the idea that justice demands the maintenance of equality of condition across persons is that starting from an equal position (or for that matter from any distribution of advantages and disadvantages taken to be just), individuals left free to choose will use their resources and opportunities in different ways, so that initial equality among free persons inevitably gives way to inequalities across persons.  Given equal money holdings, some will save and some will consume and some will invest and produce, and soon people end up with very unequal money holdings. To sustain equality of condition one would have to do one of two things: either restrict people's liberty by forbidding them to pursue their individual projects and plans in ways that lead to inequality, or continually redistribute resources from those with more to those with less, roughly from those who save and work (ants, in the fable) to those who consume and play (grasshoppers, in the same fable). Either of these policies would be morally unacceptable. So pursuing sustained social equality is a fool's errand.
