Luck egalitarianism (LE) is a theory of distributive justice, first elaborated during the 1980s (Knight and Stemplowska 2011). While it shares the strong emphasis on equality common to all brands of egalitarianism, LE provides a justification for pockets of inequality—if the inequality has arisen in a way that meets certain desiderata. One may thus speak of LE as a kind of tempered egalitarianism. The desiderata in question concern issues of choice and risk taking, and so (voluntary) choice has a special place in LE theory as the normative force distinguishing LE from outcome egalitarianism. Whereas outcome egalitarianism holds that inequality between individuals should be neutralized (ceteris paribus), LE holds that this rule applies except when the inequality has arisen due to the individuals’ voluntary choices. The term “luck” in “luck egalitarianism” derives from a pivotal 1981 article by Ronald Dworkin, which discusses the policy implications of what Dworkin calls “brute luck” and “option luck”, respectively (Dworkin 1981). In common parlance, “option luck” is translatable to the outcomes of voluntary choices.
If it is accepted, luck egalitarianism may be of great relevance to health care ethics, especially in matters of priority settingFootnote 1. One application of LE to the health care arena, here labelled “luck egalitarianism in health care” (LEHC), argues that there is no injustice in situations where someone has worse health than another, if this inequality is due to the person’s voluntary choices in the health area (Bognar and Hirose 2014). Consequently, a proponent of LEHC would holdFootnote 2 that there is no justice-based call to remedy such health inequality, and giving health care to those whose health is worse as a result of their own past choices should not be prioritized. As a clinical example, LEHC typically holds that a smoking lung cancer patient should be down-prioritized for treatment in comparison with a non-smoking patient (who presumably did not invite the disease by risk taking behaviour). Exactly how such down-prioritization is achieved—by giving the smoking lung cancer patient less treatment than the non-smoking patient, inferior treatment compared to that of the non-smoking patient, or treatment after the non-smoking patient – are practical questions that will not be dealt with here.
It should be noted that by most accounts the ethos of LEHC applies only in situations of scarcity (Segall 2009; Duus-Otterström 2012). That is, LEHC would down-prioritize the smoking lung cancer patient above only as long as not doing so would make the non-smoking lung cancer patient worse off. This is because the justification of down-prioritization in LEHC derives from a consideration of the harm or opportunity cost to third parties that arise as a result of one person’s imprudentFootnote 3 health behaviour. (For a fuller background of the notion of opportunity cost, see Drummond et al. 2015). Here, the relevant third parties are prudent patients, prudent tax payers, or both. Two different kinds of opportunity costs are relevant in this context. The first is the cost in terms of lost health (or health care) that would befall the non-smoker if the two patients described above were treated similarly in a situation of scarcity. The second is the cost in financial terms that would befall prudent tax payers or insurance premium payers if they have to co-finance the extra health care needs generated by others’ imprudent actionsFootnote 4.
The concern to protect the prudent third party from any costs generated by others’ imprudent actions is important to differentiate LEHC from theories of desert (Segall 2009). The matter is of some importance, as some policy choices made by ‘desertists’ coincide with those suggested by the LEHC ethos. Yet the theories differ regarding their underlying motive. The best way to set the theories apart is to remember that LEHC is an offspring of egalitarianism, whereas desertism is not. Although desertism may occasionally function to equalize inequalities, it does not care about equality as such. Thus, in situations where there is no opportunity cost LEHC would strive to neutralize all health inequalities, whereas desertism would not necessarily do soFootnote 5.
This article will proceed to examine the merits of LEHC critically. In so doing we will accept, for the sake of argument, what we see as the core ethos of LEHC: that health care policy should reflect individuals’ responsibility for their own health. What we seek to investigate, more specifically, is whether this ethos can be operationalized to the point of informing real world policy without straying from its own ideal. First, we will claim that a recurrent critique of LEHC—that it relies on morally arbitrary assumptions—can actually be met by drawing up a principled definition of imprudence, at least to some extent. In doing this, we clarify what critique LEHC can avoid, which brings us to the more fundamental problems with LEHC. Moving on, we will discuss the important choice of ex post versus ex ante policy approach in LEHC. We will claim that the ex post approach is plagued by epistemic difficulty and furthermore that it targets only a subset of the imprudent, without there being an ethical difference between this subset and the subset which is not targeted by the policy. This makes the ex post approach unsuitable as an expression of the LEHC ethos. However, the ex ante approach also targets only a subset of the imprudent, and furthermore it severs the link between imprudent action and outcome in a way that undermines the justificatory strength of the LEHC position. Thus, we propose that none of these approaches work to the benefit of LEHC, yet we see no third approach. We then turn to the question of policy threshold setting in LEHC, and propose that using a circumscribed version of LEHC risks “pampering the imprudent” and making LEHC nearly irrelevant. Conversely, using a more impactful LEHC version invites charges of abandoning negligent victims, unless LEHC is made part of a pluralist value theory. Coupling LEHC to other, overriding normative theory elements also risks robbing LEHC of much of its normative importance.
All in all, we believe that even despite its intuitive punch, LEHC is unconvincing as a theory of distributive justice in health care. This remains the case even if the theory is made as strong as possible.
Before undertaking this task, we should like to acknowledge that our discussion by no means exhausts the possible challenges to LEHC. For instance, several practical problems regarding the set-up of LEHC policy remain (see above). Nevertheless, if the arguments that we put forth are successful, they point to more fundamental problems, making the need of further fine-tuning of practical details less imperative.
