Seems to be working pretty well in the Scandinavian countries.

Interestingly, while Denmark has very low wealth inequality, Norway's is only middling, and Sweden's is the highest in Europe, in the same range as the US, Brazil and Russia. The Scandinavian countries have very low _income_ inequality (post-transfers).

Income equality is probably more important than wealth equality in terms of quality of life, but wealth inequality isn't nothing.

(Also you have to be a bit careful with wealth inequality figures, as they can be distorted by local practices; for instance in some countries where defined benefit pensions are standard, such a pension, even though clearly valuable, may not be assessed as wealth, and in some countries it may be common to have a long-term/effectively life right to a fixed-cost rental, which again, is wealth-like, but probably not assessed as wealth.)

You mean the ones who are selling so much oil they put a lot of it in a sovereign wealth fund? Sure.

I think the real question is how to make it work without oil money coming in. Without the constant extra help from foreign countries that money buys. France has some, but not much. Certainly not enough to cover all state expenses and have left over.

They have A LOT of rich people.

The thing is people don't care about how many rich people there are out there, as long as they can get a good life out of their labor (good job, good house, etc) but since capitalism has optimized these out of the reach for most people nowadays, then they start to blame rich people for everything, with the definition of the word 'rich' here being very fluid, ending up to mean just about everyone who has more than they do, and not just your Bezos, Musk and Saudi kings, so any taxes on the "rich" ends up only on the hard working middle class again.
