We've the same problem over here in Sweden, with (mostly) eastern europeans being employed for less than what a Swedish worker could even pay rent with.
They pack themselves into tiny apartments in the shoddy areas of cities (or live in cars or at sites), live off substandard food, and work 14 hours a day, 7 days a week (which, by the way, is against Swedish labour law).
For example, I met a couple of Lithuanians at a site last year. They told me they lived off nothing but cheap chease, cheap bread, and even cheaper coffee. They also told me that whatever they didn't need themselves, and whatever they didn't send to their families, they used to import cheap alcohol and cigarettes, which they either used themselves, or sold. The proceeds went into doing the same thing again and again.
I've got no trouble with the ones who actually move here, and live by the same rules and conventions as the "natives". However, those who accept pittance for pay and dump the prices, devalue everyone else's work, including mine, and that makes me bloody livid.
Ultimatly, it's the fault of those who hire them, but it's the "poles" (which has become slang for everyone of eastern european decent now...) who get most of the blame. I've met a few "good" migrant workers, but most of the ones I've met have been completely mindless dollar-drones who take pride in being the cheapest of the truly cheap. That is worthy of, atleast, my resentment.
(Add.)If I was a migrant worker, and undercharged that much, and lived under that bad conditions, I wouldn't feel pride, I'd feel shame! Shame for whoring myself, and for shame for soiling the reputation of my country and my countrymen!
