I'd like to point that Vancouver is a destination city for Swedes.
We've always gone aggressively after them when other teams tried to avoid Europeans. It was the same from czechoslovaks for awhile too.
We now have Legacy players scouting for us and finding superstars.
I think there's some truth to that. And they should continue to foster it as it almost certainly derives from word of mouth from prominent Swedes over the years that have spoken well of their experience.
As someone who lives just outside NYC and works in Manhattan, I can speak with firsthand experience that there is definitely a built-in structural advantage when it comes to recruitment. The biggest factor, I've found, isn't the spectacle (shows, concerts, museums, shopping). Rather, it is the role of the trailing spouse/family in the decision making process.
New York is so big that it has depth in just about every major field: banking (obv), advertising, tech, film, biotech, academia, tourism, dining, etc. This makes the two body problem much easier to solve in terms of finding a suitable position both partners. Also, there's specialized schools for most major languages: Russian, Japanese, Chinese, French, German where their kids receive immersion education that facilitates when they move back.
