According to Fareed Zacharia, Bernie's Scandanavian utopian dream is not what he claims.  He may even believe it, but if he does it is because he has not done the research.

Sanders’s vision of Scandinavian countries, as with much of his ideology, seems to be stuck in the 1960s and 1970s, a period when these countries were indeed pioneers in creating a social market economy. In Sweden, government spending as a percentage of gross domestic product doubled from 1960 to 1980, going from approximately 30 percent to 60 percent. But as Swedish commentator Johan Norberg points out, this experiment in Sanders-style democratic socialism tanked the Swedish economy. Between 1970 and 1995, he notes, Sweden did not create a single net new job in the private sector. In 1991, a free-market prime minister, Carl Bildt, initiated a series of reforms to kick-start the economy. By the mid-2000s, Sweden had cut the size of its government by a third and emerged from its long economic slump.

This also struck me, considering his absolute hatred of the 1% here in the USA:

Take billionaires. Sanders has been clear on the topic: “Billionaires should not exist.” But Sweden and Norway both have more billionaires per capita than the United States — Sweden almost twice as many.
