Sadly no, benefits will often pay as much as the lowest income jobs so people have little or no incentive to get off them.
The possibillity of unlimited free education counters it somewhat though, and our population is highly educated for the most part.
The benefits of our welfare system is that we have no poverty, and people have limitless possibillites. The backdraw is that our welfare system acts as a draw for low educated immigrants, since the state guarantee everyone a decent living in Norway. We have some shocking numbers when it comes to employment for Somali immigrants for example, shocking to the degree of 8\10 of the females claiming benefits.
It is not sustainable, and it is why I am so glad that the political spectrum in Norway has shifted towards the right, and it seems permanent.
