I have mentioned before that emigration of native Belgians, Brits, Germans, and Dutch is increasing yearly. Now it's the Swedes. Immigrants from Muslim countries continue to have children at far above replacement value, native Europeans far below, immigration continues, and now this. Demography may be destiny. The nations of Europe seem to be completely unable to integrate and absorb immigrant peoples. This is because their nations are founded on tribes. America and Australia, less so Canada, are founded on ideas rather than tribes. That's been working a lot better, frankly.
Europeans remain highly suspicious of nationalism because it so easily deteriorates into racialism. It does in Europe, anyway. The nations of Europe are still highly associated with tribes that are centuries old. The Hungarians call themselves Magyars after the tribe that moved in from Asia a thousand years ago. Most of the national movements of the 18th- 20th Centuries had very clear ideas of True Romanians, True Finns, etc. They disliked and often feared those lived among them who were tribally different. Montenegrins just split off from Serbia. The Flemish and the Walloons are still distinct in tiny Belgium. Hatred of Jews and Gypsies and wars over tribal dominance were not 20th C aberrations caused by Germans in Europe. They are Europe.
We have, er, very little animosity between the Flemish and Walloons in America. None to speak of between the Serbs and Croats, even. To get conflict going in America, you have to have really obvious differences: language, dress, color. Even with those, we seem to adjust far better than say Paris or Lille, Rotterdam or Oslo. America does better integrating races from different continents than Greeks or Letts do different dialects. In Europe, nations have a great difficulty defining themselves as anything but historical tribes. Great Britain does best among them, but even the UK has had notable conflicts with Ireland, and still has separatist movements.
Can anyone imagine a popular separatist movement in America? Even to divide races into their own states- certainly a sharper visual divider than Spaniards and Catalans and Basques - attracts only fringe support. (God be praised). You don't have to be descended from anyone in particular to be an American. Any ancestors will do, really.
This quiet emigration is how many western Europeans are solving their Muslim immigration problem. They're moving to New Zealand or Canada, or even (gasp) America. Having no way of defining their nations other than by soil and race, there isn't much hold. Language and foods you can take with you (and kid yourself that you'll pass them on to your children).
One more thing. It's not the elderly who emigrate. Even the middle-aged are underrepresented in mobile populations. The people who are leaving are predominantly those who would have had nice little Dutch or Austrian children to dress up. Europe is vanishing. The English colonies really are very different in the world. Even India is learning how to absorb differences.
