 On the other side, the egalitarian “fair chances” approach can hardly be the whole story since the only allocation strategy that fits a purely egalitarian approach is random allocation or a lottery. A lottery is vaguely fair when the two potential beneficiaries incur the same costs and benefits, but not when the benefits accrued from a resource are hugely different, or when other considerations, such as urgency, enter into the calculation. Some egalitarians have backtracked from pure randomness of a lottery (so that the asthmatic in the above example would have a somewhat lower chance of being successful—see Brock 1988; Broome 1988, 2004). Others have argued that considerations like urgency, the level of overall health need, or age should affect the proportional chances of success (Kamm 1993). Yet others have insisted that the asthmatic has already lost the “natural lottery” by having a serious health condition, so there is no need to run another lottery (Menzel 1989). These attempts aside, the lottery approach is not greatly favored, except as a last resort.
