Norway will not issue a work permit for immigrants, if their work contract pays less than is typical in the industry. So this loophole is accounted for. Once an immigrant has permanent residency (or arrives due to marrying a Norwegian) then this could become a problem, but by then they have hopefully integrated enough, and will no longer work for peanuts. The cost of living being so high here probably discourages that anyways, and the things the sibling commenters stated also apply.

Thank you for responding, it seems like you were the only one to understand the problem and explain how it is mitigated there.
