But I don't follow your last point. Why wouldn't you expect mass migration to increase? People are more aware of the rest of the world than ever. They can look at the crap in their backyards and peek over fences more than ever. The Internet is global. The workforce is now more global than ever. Opportunity drove continental migration in America, Africa, etc.
Global tourism is as great as ever.
At the other end of the spectrum, we're seeing the rise of participatory citizenship: highly desirable workers where national governments need to compete for their residency and economic output more and more.
