The guy who wrote "the girl with dragon tattoo" was a leftwing journalist. There is no cultural epitaph of pervasive leftist majority anymore in the Nordic countries. If anything there are much more nationalist conservative right-wing views among the common population because of the recent waves of ME immigrants. The media by an large is still left.
It's true that many west european countries had very strong socialist movements for decades (not as much now though), but there isn't even possible to make such statements that it's somehow became engraved in the culture. Look at the former East Block countries, there it might be true, but then the mistrust of the public to businesses is because of the corruption. Sweden also has a fair bit of corruption, but the authorities together with lobbying organizations and media spread enough propaganda that the country is somehow the least corrupt in the World.
