because of the best functioning societies. we (used to be) high trust societies where you were able to leave your wallet on a table in a very populated place and no one would steal it. not to mention the general wellbeing being at incredibly high levels and people are very well mannered and don't want to cause any issues to anyone. on top of it societies work pretty well and things are extremely streamlined through using common sense. in short, it just works. or at least used to work before the globohomo started fucking things up by eroding the societal cohesion. on the other hand outside the nordic countries, it's normal to see absolute subhuman bullshit like trash on the streets, pickpockets and street scammers along with beggars. also graffiti all over the fucking place and dilapidated infrastructure. these are a thing in basically every large euro city outside the north. it's practically like visiting some emerging nation going to a place like paris and it has never been any better even decades ago.  nordic countries are basically japan lite and other euro nations are something entirely different.
