Not every injustice is a matter of how a fixed stock of goods is divided. Some accounts locate injustice in relationships and structures — domination, exploitation, and the arrangements that decide who holds power over whom — which can persist even under a nominally fair distribution.
Answers differ over what the defect in a structure actually consists in: subjection to another's arbitrary power, the appropriation of what others produce, or a failure to secure what people need in order to live a life they have reason to value. What they share is reframing the political question from "who gets what" to how the arrangement itself stands towards the people living under it.
