Gscholz, Norway has oil and a number or other natural resources other countries are not blessed with. Lucky Norway. Norway also has high taxes. You are welcome to them.
You might be better comparing figures with the likes of Germany or France. By any standards both should be richer than the rest. Until they reform their business and social practises. They will continue to be burdened with millions of unemployed. France may hate the 'Anglo Saxon' style liberal eoonomy. But it works for the Anglo Saxons and others.
