It really helps with the quality of life thing if your country has little or no outlays for national defense but instead has it guaranteed by the taxpayers of another country 3000 miles away.

Good for a welfare queen, maybe. If you actually work for a living in Europe, you are taxed through the nose. If Europe is such a wonderful place to have children, then why aren't they having any?

Entirely possible. But, again, for all America's pathologies, I don't see an equivalent to the nightly car-burning festivals in Paris. America's inner cities are horrifically violent, but by and large it is an intra-underclass violence without a political component that European inner-city violence has.
I personally ascribe huge quality-of-life points to Europe’s historic cities. I’d never consider living in Europe’s suburbs...as they are the same soulless wastelands as they are here, IMO. So, when the U.S. gets almost as bad or as bad as Europe, then it’s time to consider moving.
