yeah White Material is good you could argue its the bluntest film she's made but even then it's got those eliptical qualitiesoh word I somehow thought you mean the opposite thing by "captures", that makes more sense
no other examples come to mind but I doubt she was the only director addressing the IMF/global south in 2008, tho it's usually less direct than having a class of grad students just discuss it for the audience. I experienced the heyday of antiglobalization in the early 00s - the whole scene of post-Seattle huge protests against the IMF, World Bank, G8, FTAA, etc - and tho I wasn't really paying attention to film at the time I do feel like that was definitely the moment when the basic injustice of that debt peaked in Western etc public consciousness, before it was essentially wiped out and replaced by the financial crisis. I'd bet she filmed that before the financial crisis broke, in fact.
anyway, I agree, I think she's pretty good on power dynamics. one of her more recent films that I haven't seen - White Material - sounds like almost a response to the white people having character arcs and emotional journeys to an African backdrop of something like Out of Africa (which isn't even a like, bad movie, just one that would nowadays I assume at least try to give non-white characters some kind of agency, rather than just functions of the white main characters the surround). High Material is about, among other things, indentured servitude.
Weirdly i remember one guy talking about that Ridley Scott movie the counseller where he said his biggest problem with that movie is that the characters keep talking about this great evil that's coming but it never arrives whereas in White Material it does in the form of civil war and everybody gets damaged by it.
also they would do that with Out of Africa if they were to remake it today but that's also because Out of Africa is one of MANY examples of a average movie that got awards thrown at it and nobody even now understands why
