Sure! There are multiple claims in my comments, but one can get the gist by reading about the first prime minister of Norway after World War II, Einar Gerhardsen. To back up this new claim I cite the same Wikipedia article linked above:

Many Norwegians often refer to him as "Landsfaderen" (Father of the Nation); he is generally considered one of the main architects of the post-war rebuilding of Norway after World War II.

A better source might be SNL (which stands for the Great Norwegian Encyclopedia and is owned mostly by different Norwegian universities) though this source is in Norwegian only, but should be fine to auto-translate if needed.

The idea of public ownership over natural resources is something that has been a big part of Norwegian identity, and this idea is also manifested in other laws such as the Freedom to roam law, which essentially states that it is

(...) the general public's right to access certain public or privately owned land, lakes, and rivers for recreation and exercise.

Though I would argue much of this identity has been lost in the last 50 years, I am also proud of some of the accomplishments of Norwegian social democracy and think it shows that the idea that "class collaboration is betrayal of socialist values" is wrong. At the same time it is important to admit that there have been problematic parts throughout its development, such as the treatment of the Sámi people and other minorities and the illegal surveillance of suspected communist sympathizers, to name a few.
