Norway doesn't care. It is a country with a reputation for good governance and northern-European economic strength. But economically, it is a country that is largely a gas station: like a democratic Russia with more competent governance.

Over half its economy is based on oil and mining. It has failed to develop meaningful economic diversification, and, because it has wisely banked so much of the proceeds of its oil (over US$300k per capita), there's not a lot of pressure to adapt.

Norway will not be a center of innovation anytime soon, except in oil-related fields. Eventually, as oil gets replaced as a source of energy, they may feel more pressure to change. But for now, they suffer from a more sophisticated version of the resource curse.

Sweden is an interesting counterexample, which has a lower GDP per capita but a much more diversified economy. Sweden abolished a wealth tax they used to have almost 20 years ago.

Over half of the value of exports is oil and mining, but oil production, mining and quarrying directly employ only about 23,000 people, compared to 190,000 in manufacturing for example.

Because such a large portion of the oil proceeds are banked, it also distorts the rest of the economy far less than it otherwise would. Unless you live in very specific parts of Norway, you can go your entire life with hardly any exposure to the oil industry directly, or secondary interactions with major suppliers to the oil industry.

Norway has a good oil refinery industry though. They refine oil from other places because they're so good at it.

Is this tax because the state needs the money or is it social engineering?

In a nutshell, Norway can afford to have some mildly self-sabotaging economic policies.

The rest of europe absolutely cannot (but that won't stop them, just like with rent control).
