Scandinavian countries are not “super socialist” - sure, we have robust social welfare systems, but these are funded through taxation on regulated market economies with private ownership. That is not socialism.
I know that there were some experiments with trying to transfer into a socialist system here in Sweden during the 70s (I think?), but those failed in a spectacular fashion and were rolled back. They are the reason that many famous “Swedish” brands such as IKEA aren’t actually based in Sweden.
