Equality of sacrifice

Equality of sacrifice is a term used in political theory and political philosophy to refer to the perceived fairness of a coercive policy.
John Stuart Mill noticed that citizens often view taxation laws as being fair, as long as taxation is also applied equally to everyone else in society. Political theorist Margaret Levi applied the term to the perceived fairness of conscription in democracies, to which citizens may consent as long as conscription is enforced as a universal duty – as opposed to elitist and exceptionalist policies, as it will sometimes occur in partial mobilization.
