Oh, if you're wondering how the "lower/servant class" can manage to afford to live here, wonder no more: They just overcrowd houses. 3 bedrooms, 8 people, that sort of thing.
Don't forget the very very generous government housing subsidies handed out right and left. Those are a big part of the housing boom here on this part of the border --- another goodie provided by the taxpayers --- the government is practically giving housing away.
