I'm not sure about Bhutan, because I've never been there, but for sure I think that middle-class life here in Romania (for those that can afford it) is a lot better and more relaxed than middle-class life in Norway (for starters, people here in Romania don't have to fear the State taking away their kid at a moment's notice, as it happens in Norway). Which is to say that those "charts" are very deceptive.
