Norway has twice the oil reserves of Scotland with roughly the same population. Plus, a very large already accumulated oil wealth fund that can’t be replicated by Scotland.
Norway has no equivalent of the Scottish division between the Catholic Highlands/Hebrides and the Presbyterian Lowlands. The Laplanders/Sami People are a tiny tiny fraction of the Norwegian population.
Norwegian Social Democrats don’t have the visceral hatred of the wealthy and desire to destroy the upper class. They just want the money to support a cradle to grave welfare state. For the Scottish Left, that is just one goal.
Sorry, the Highland/Lowland religous split has been irrelevant since the time of Sir Walter Scott.
