The proper name for "perpetuate injustice without racist intent" is "classism". It can happen in homogeneous countries just as well.. in fact, I grew up in Russia surrounded 99% by other white slavs, and I'm super culture-classist based on that experience. I've also heard from other Eastern European immigrants how it's awesome that in America (compared to at home) it's easy to live not being surrounded by gopniks (chavs in Britain), bydlo (lit. cattle - kinda like urban white trash), and alcoholics, and how they wish Moscow/Warsaw/whatever had more class segregation accessible to an average person, instead of just the very rich. It's a bummer that in America class is so tied to race.
