Norway is an interesting case study. They don't have that much going on but what they do have going on. Their leaderships have manage it superbly and they always their people first compared to many countries who either spend lavishly or all lost due to corruption. However, I'm a bit surprised they didn't lower their tax rate gradually since it's so high. Despite this, I would say that Norway won the oil lottery. I wish my country, Nigeria will learn a lesson here. Our politicians are so corrupt that even the oil revenue put into government treasuries is stolen by government officials. That leads to the underdevelopment as you rightly mentioned in your video.
Yeah, I think this was the case for them, during world war, or after, post-war and the political changes that was sweeping Europe that time, Norway stood it's ground and the people running the government really knows what to do.
And so they become totally independent and they have a lot of policies that prioritized their people so that their economy will keep going. And with that, they totally re-created everything and in the last 50 years, they really make a big changes and now becoming one of the wealthiest or at least many people wanted to live their because it's rich country and also very quiet.
Also they actually did elected people who would do the best help for the government, and not the most popular person who says what they want to hear. That is the type of situation politics in everywhere else, in fact in most cases people are voting for people they dislike, because other side have people they hate, so it's clear that Norway and many other Scandinavian countries are shown as good examples of why they are run very well, its because if you are just a popular moron who lies all the way to election, people will just not vote for you.
Many politicians who are presidents right now, would not go beyond 1-5% range in Norway, because Norway only cares about development and actual action. Many people in politics grow from smaller positions, and do something good with their small position to get to a higher position, if they suck and corrupt then they don't win anymore.
If you keep that simple fact in mind, then you are going to end up with something quite good, and get a greater result in the end. I believe that Norway has done that, they realized that if they do the right thing and just run the nation good and well, they can keep their job and even improve, so politicians try to help as much as they can.
