I am not sure why wikipedia disagrees with you. Probably because Norway is not a socialist country. Government is not equal to the workers. If workers owned means of production, it would have been a socialist country. This is simply not true. Most of companies in Norway are not owned by workers.

I gues this will help you to understand:

"Ownership: In a capitalist economy, property and businesses are owned and controlled by individuals. In a socialist economy, the state owns and controls the major means of production. In some socialist economic models, worker cooperatives have primacy over production"

Finally, no socialism never has been working very well. There is not a single example of it working well in all recorded human history.
