The NY Post had an amusing article about the myth of Scandinavian happiness. There are serious problems with the essay, as it collects together a mishmash of semi-related items, some backed up by evidence, some just blowing, uh, smoke out its nostrils. There is an air of college BS term paper, where you have some general knowledge and a few anecdotes, trying to rope all that together into proving some point or another. I recognise this because of nostalgia.
Nonetheless, even applying a 50% discount on the facts here, I think there is something to it. And it's fun.
