I need to write a paper regarding a social injustice, but I can't think of any good ideas. I was thinking maybe the fact that people today feel like they need to pay reparations to modern Blacks because their ancestors were slaves is a social injustice, but I don't really know what to do with that. So I need a new idea.

Some things I've already thought of that I'm not sure about:
*Opposition to interracial marriage
*Repulsion of people different from ourselves
*The idea that I explained above, including affirmative action

Social injustices?

Death penalty
poverty
war injuries
lack of uniform health care
