Småland is the origin of many Swedes that settled in the America's Midwest. (See books by Vilhelm Moberg, "The Emigrants," etc.)
Most Americans are descended from Europe. I believe the subset that risked a lot to come to North America, were superior to those who remained behind.
Those who remained behind suffered dictators, two horrific wars, socialism, and now are surrendering to islam-to a degree that should make us nervous.
