" There may be something inherently selfish in the social service states of the mid-20th century: blessed for a few decades with the good fortune of ethnic homogeneity and a small, educated population where almost everyone could recognize themselves in everyone else. Most of these countries—self-contained nation-states exposed to very little external threat—had the good fortune to cluster under the umbrella of NATO in the post-1945 decades, devoting their budgets to domestic improvement and untroubled by mass immigration from the rest of Europe, much less further afield. When this situation changed, confidence and trust appears to have fallen off. "
