Yes, why not? To the best of my knowledge Norway is still thriving. Ideally more countries would get on board with such ideas and there will be fewer palpable places for them to relocate to.

From the article, “The model in Norway is that everyone should contribute relevant to ability and therefore those that have a greater ability to pay taxes, should pay a little more.” This seems more than fair, particularly while failing tax systems are leading to unprecedented levels of inequality.
