When I tried to get residency in Canada as a Software Engineer I was told by my local MP to get a minimum wage job for two years at Walmart, McDonalds or Canadian Tire because they had rubber-stamp approval with the government, and it was the easiest way.
In my town, all the immigrants worked at those places, and they lived 15 to a small house. Not surprisingly, no Canadian was willing to do those jobs.
While obviously not nearly as bad as the conditions in the article, it's certainly in a similar vein.
