There are a lot of common sense ideas in the Scandinavian countries.
I've been thinking about it and I think that perhaps it's related to their increased tolerance for failure. A Swede or Norwegian or Finn is able to say "yes, this was a mistake" and not be derided in public for it.
The concept that humans aren't perfect isn't lost on these people as it seems to be in much of the rest of the world.
Another great example of this is the sex offender registries in the area. They're not only non-existent, they're actually illegal. They contend that it is a gross violation of personal privacy for those who already served their time and point out (probably correctly) that they do very little than encourage fear and paranoia amongst the populace. There was even a very public protest in OPPOSITION to a group who set up a private registry with similar information, after which, the site was removed due to its illegal content (in violation of local privacy laws).
To bring up another example, in these countries, there are very few frivolous lawsuits, as the system is carefully balanced to make it burdensome to bring one.
It is much easier for a judge to deem the plaintiff liable for all court costs and all defense costs if he feels the lawsuit was brought with malice or with little hope of succeeding.
Additionally, the state represents both parties in some cases, removing the financial burden of defending yourself from lawsuits. What they then do is place that burden on one of the parties in the case that they have been shown to be "willfully" out of compliance with civil law, but in cases where it is a genuine misunderstanding, the costs are absorbed by the system.
Rather than having a heirarchy where the rich can do whatever they want and the poor get fucked. Or a system where the powerful control everything and those down on their luck are brazenly left out to dry, these countries seem to have found a balance.
Also, worth noting, that these countries, despite their low populations and high standard of living, are not in the list of struggling economies, even during this "European crisis".
Absolutely brilliant. :-)
