 While these sufficientarian approaches avoid the leveling down objection, they nonetheless face two significant challenges. First, should governments be indifferent regarding health disparities above the threshold identified by sufficientarian views (Arneson 2002)? If the threshold is set too low, such a view may regard significant disparities in morbidity and mortality as not unjust. Second, among those who fall below the threshold, who should be prioritized (Fourie 2016)? Should policymakers focus on maximizing the number of people who meet the threshold, even if this means helping those who are better off? Or should they prioritize the worse off, even if this means using significant resources to only marginally improve their health? (For a discussion of possible solutions to these problems, see Shields 2016).
