What’s Unjust about Structural Injustice?

Structural injustice is either wrong or not. A deontic view, on which there is no injustice except agents' wrongdoing, may have trouble reaching such intuitive cases as structural sexism, and especially structural class inequality. An alternative telic approach, on which injustice is bad but not wrong, can reach those cases. But how could injustice in that telic sense warrant resentment or righteous anger, as it seems injustice must? I press the dilemma to scrutinize not only the current idea of structural injustice but also a wider swath of views about justice, and I critically consider possible ways out of it.
