But this vision of homogenous, altruistic Nordic lands is mostly a fantasy. The choices Nordic countries have made have little to do with altruism or kinship. Rather, Nordic people have made their decisions out of self-interest. Nordic nations offer their citizens—all of their citizens, but especially the middle class—high-quality services that save people a lot of money, time, and trouble. This is what Americans fail to understand: My taxes in Finland were used to pay for top-notch services for me.

When I lived in Finland, as a middle-class citizen I paid income tax at a rate not much higher than what I now pay in New York City. True, Nordic countries have somewhat higher taxes on consumption than America, and overall they collect more tax revenue than the U.S. currently does—partly from the wealthy. But, as an example, here are some of the things I personally got in return for my taxes: nearly a full year of paid parental leave for each child (plus a smaller monthly payment for an additional two years, were I or the father of my child to choose to stay at home with our child longer), affordable high-quality day care for my kids, one of the world’s best public K-12 education systems, free college, free graduate school, nearly free world-class health care delivered through a pretty decent universal network, and a full year of partially paid disability leave. As far as I was concerned, it was a great deal. And it was equally beneficial for others. From a Nordic perspective, nothing Bernie Sanders is proposing is the least bit crazy—pretty much all Nordic countries have had policies like these in place for years.

But wait, most Americans would say: Those policies work well because all Nordics share a sense of kinship and have fond feelings for each other. That might be nice if it were true, but it’s not, as anyone who has followed recent political debates about immigration or economic policy in Nordic countries understands. Nordics are not only just as selfish as everyone else on this earth but they can—and do—dislike many of their fellow citizens just as much as people with different political views dislike each other in other countries. As for homogeneity, Sweden already has a bigger share of foreign-born residents than the U.S. The reason Nordics stick with the system is because they can see that on the whole, they come out ahead—not just as a group, but as individuals.

Even so, surely these Nordic “socialist nanny states” pay the price in squashing entrepreneurship and business innovation? This is another refrain I repeatedly hear: Nordic countries have produced no Steve Jobs, no General Motors, and no medical breakthroughs. In short, American entrepreneurs, scientists, and other innovators have changed the world while Nordic countries fall short of taking risks and working hard. This is what Hillary Clinton implied when she responded to Sanders’s praise of the Nordic region in the first Democratic debate. “When I think about capitalism,” Clinton said, “I think about all the small businesses that were started because we have the opportunity and the freedom in our country for people to do that and to make a good living for themselves and their families… And I think what Senator Sanders is saying certainly makes sense in the terms of the inequality that we have. But we are not Denmark. I love Denmark. We are the United States of America.”
