In the ordinary course of life, choices vary with age and other factors because one’s opportunities vary with one’s circumstances. Thus, investments in and expenditures on healthcare (and most other things) vary with age and a variety of other factors, including whether one lives in a rural area, suburb, or central city, health risks, risk aversion, and beliefs about the nature of a good life. Because assessment of the effects of illnesses vary with the same factors, the conclusions reached about best private and governmental health policies also tend to vary. This implies that conformity to “ideal” pandemic policies is more likely to be generated by a federal or polycentric system of policy making than a unitary system, especially ones that are constrained by a generality principle.

在日常生活中，选择会随着年龄和其他因素而变化，因为机会因环境而异。因此，对医疗保健（以及大多数其他事物）的投资和支出会随着年龄和各种其他因素而变化，包括一个人是住在农村地区、郊区还是中心城市、健康风险、风险规避和对自然的信念的美好生活。由于对疾病影响的评估因相同因素而异，因此得出的关于最佳私人和政府健康政策的结论也往往不同。这意味着与“理想的”大流行病政策相符的情况更有可能是由联邦或多中心的政策制定系统产生的，而不是单一的系统，尤其是那些受普遍性原则约束的系统。
