Final answer:
Michael Sandel recognizes various methods for allocating military service, including conscription, allowing paid substitutes, and market systems; all reflect different ethical and practical considerations for military mobilization.
Step-by-step explanation:
The question asks about Michael Sandel's perspective on different methods of allocating military service. According to Sandel, there are indeed different ways societies have organized military service, including conscription (compulsory service); allowing those who were drafted to hire paid substitutes; and market systems, where individuals choose to enlist, often for a price or benefit. All these methods reflect varying ethical and practical points of view on how to mobilize a military force. In historical context, during peacetime between 1870 and 1914, European powers significantly increased their military sizes through conscription, exemplifying one of these approaches.
