Meanwhile, something like 1/3 of the market cap on the Oslo Stock Exchange is state owned, the second largest media group is owned by a public benefit corporation, the largest bank is owned 34% by the government and ~10% by a foundation with a public benefit mandate. At the same time Norway has a more expansive welfare system than most supposedly socialist countries.

It's fair enough that they're not fully socialist by any means, but for a lot of socialists the Nordic model is far closer to what they want than e.g. China.
