The Nordic model is a social democratic one, which is still fundamentally a capitalist one. This is what someone like Bernie Sanders claims to want.
Sanders gets away with calling himself a socialist because Americans have forgotten what https://en.wikipedia.org/wiki/Socialism actually means: “social ownership of the means of production, as opposed to private ownership.” Americans have forgotten what socialism means because the American socialists were persecuted into obscurity in the 20th century. So now even the vocabulary for socialism is lost in Orwellian fashion.
