Norway has about 4 million people and is one of the largest oil exporters in the world. Nice gig if you can get it.
As for Denmark and Sweden, they have moved away from Socialism for one thing.....check out their corporate tax rates. They have long been WAY lower than ours. For another, if you look at the period when Sweden grew rapidly, it was before they imposed all the socialist policies. Their economic growth slowed way down after they did that. That’s why they rolled back some of the socialism. No country has ever gotten wealthy through socialism. They only places where it has not been as bad were places that had already become wealthy - via free market economies. Even then, their growth rates came way down once they imposed more and more socialism.
I don't think socialism is defined by corporate tax rates.
What social services have they cut back?
