The question of women from Asia and Eastern Europe being forced into servitude came up recently on this blog. I would not normally link to the LA Times, which has a deserved reputation for inaccuracy. In other words, this may be another urban legend. But the story fits with what is known about North Korea.
It also ties in with the demographic discussion going on in the threads below. When the First World has a shortfall in people, it "imports" more of them, via immigration. When the Second World (or Eastern Europe), has a people shortage, it also seeks to make up the shortfall from somewhere. In either case, the process is not always pretty.
