If you see the poor oppressed in a district, and justice and rights denied, do not be surprised at such things; for one official is eyed by a higher one, and over them both are others higher still. The increase from the land is taken by all [the officials]; the king himself profits from the fields. (Ecclesiastes 5:8)The less money you have, the harder it is to get any, and the less influence you have. This happens on an individual scale, and it happens on the levels of countries. What's the modern equivalent of the king? Perhaps the shareholders of the big corporations.
Note that the fact we shouldn't be surprised doesn't mean that we should be indifferent.
What I find more disturbing is when such things happen and people (including Christians, who ought to know better) don't even see them.
Interesting tie-in with a thought-provoking book set in a post-apocalyptic world that I'm wading through at the moment, called "The Gone-Away World" - about which more when I finish it.
