It is equally interesting to look at Nordic Americans, a group that combines the Nordic success culture with U.S.-style capitalism. It was mainly the impoverished people in the Nordic countries who sailed across the Atlantic to found new lives. And yet, as I write in my book, Danish Americans today have fully 55 percent higher living standard than Danes. Similarly, Swedish Americans have a 53 percent higher living standard than Swedes. The gap is even greater, 59 percent, between Finnish Americans and Finns. Even though Norwegian Americans lack the oil wealth of Norway, they have a 3 percent higher living standard than their cousins overseas.

Perhaps even more astonishing is that Nordic Americans are more socially successful than their cousins in Scandinavia. They have much lower high-school-dropout rates, much lower unemployment rates, and even slightly lower poverty rates. Similarly, immigrants to the Nordic countries fare worse than those to the U.S. with regard to employment, self-reported health, and the school results of their children.
