I'm not quite sure about the meaning of "stol på kapitalismen", but I'm inclined to say "trust in capitalism" instead of "rob capitalism".

En référence à cette discussion, j'ai une question: où est la musique de cette chanson?

I think this song is interesting also from a specifically linguistic view. It is written in a language form which is neither traditional bokmål, nor nynorsk. A language movement was developing in Norway in the 60s and 70s, trying to mix both traditional language forms into a “Common Norwegian” (Samnorsk) sharing the characteristics of both and, at the same time, reproducing the popular language of larger towns in South and West Norway (the most densely populated areas in the country). This had also political associations: the “Samnorsk” supporters were mostly associated with the Left, while conservatives kept on adhering strictly to traditional bokmål, the mixed Dano-Norwegian literary language prevailing in Oslo, and used in the media. A certain number of Samnorsk forms (e.g. the feminine gender of nouns with [-a] definite article or possessive adjectives placed after the noun, e.g. “jobben din”) are now generally accepted and used. All song lyrics by Frosk are written in Samnorsk.

I must admit that it's a bit hard for me to understand how Norway, a small nation of five million people, can afford to have several Norwegian languages, i.e. a potential source of so much confusion and misunderstanding. That, at least, cannot have anything to do with the North Sea oil.
