> I feel really sorry for them. One of the project managers lived in a rented bedroom of another Indian family with his wife and daughter because he couldn't afford a place of his own. Another guy, single, lived in a shared 2BR house with 8 other people for the same reason. And there were more people in the same situation.

I see your point and in no way do I advocate for people being treated that way in US. But the viewpoint of many of the workers who accept these arrangements is that its better than what they had back home, or some variation of that argument. I'm not sure how to argue with that.
