I had sympathy for you before you said middle class. Just kidding! That's happening in an area near where I used to live. The place is run down, an it's rough, an it's better for all involved if it is all knocked down an rebuilt. The people who had to move got paid the highest price they could possibly get if it was up for sale. So they didn't really get a bad deal. An since the place is a dump anyway, most people are glad to get out of there. So it's not always a bad thing.
