The USA surpassed Norway's median income some time in the 2020's. And it's VASTLY cheaper to live in the United States.
The Nordic petro states were never really that impressive to me personally. I'm sure someone will come out of the woodwork to talk up their healthcare and social services, but again, if you were being fair we would compare them to a State like Massachusetts instead of Mississippi or Alabama and you would find our healthcare systems here are equally if not more accessible.
