capitalism and the structures of violence and oppression are essentially the same thing, so the quickest way I know of to get a crude idea of how disprivileged a particular person or a particular minority is, is to look at their income.
a lot of people who don't think in terms of intersectional analysis (whether they claim to or not) would likely be surprised by what looking at people's income actually tells you.
it's not perfect by a long shot, and there are a lot of nuances it doesn't take into account—but it does get you a long way towards grasping the big picture.
bonus points of you use purchasing power parity for an (again: crude) more global perspective.
