For instance, the health care is a centralised system. Those never work. Doctors don't have time/incentive to diagnose problems unless they are obvious (or you're related to a politician -- yes, like in Soviet). Many Swedes (how many? No one knows) drag easily cured problems around for years and decades.
From my own and friends' experiences -- simple knee problems that stopped favorite exercise, lack of iron/vitamines that gave depressions, hard to recognize allergies that resulted in tiredness, thyroid problems etc.
I am here to tell you Scandinavians that it doesn't have to be like that!
If you go into a health care place in Romania, you are a valued customer they want to make happy. They will screw you over by giving you extra tests, not telling you something (anything) to get you out the door (because they only have minutes with any given client)!
You can't get that for money in Sweden. If you have health care problems, go to East Europe or something for the next vacation. (A recent article on BBC discussed that Polish doctors were working in Britain, because Polish immigrants were spoiled with the health care and the British system seemed similar to Sweden).
Please remember this when you're too chronically tired to make enough fuss so the doctors will try to find your problem to get rid of you.
(I have experience with the Swedish and partly with the Finnish health care systems, e.g. the Norwegian is a bit different but I don't really know enough to have an opinion.)
