And I don't know what you mean with "captive tax base" but Norway just piles up the wealth they are too afraid to use it since it will increase the inflation.
Norway is the one that actually makes it work. Their GDP per capita is slightly higher than the US and more than $30,000 higher than the other Scandinavian countries.
