You don't question economic immigration, WAV - your entire philosophy centres around culture & enthicity and the supposed dangers of what happens when people lose their cultural identity. Your notion of Culture is a volkish fantasy based on dodgy notions of racial purity & Nationalism, which you further compound by hiking it to the Occult in your espousals of a Global Christianity which is somehow in sympathy with your Nice Multicultural World. Basically what you want is a totalitarian segregated world order of enforced Bogus Folk Culture maintained by each Nation State for the purposes of Tourism. As dystopian future visions go I'd say it doesn't get any grimmer than that!
