I don't know how to test it, though I suspect the relative absence of christian beliefs in those countries would make a difference. And why would such a "window" even exist there? If these countries can figure out how to keep economic progress going indefinitely without the dysfunctions in Western societies identified by, say, Peter Thiel, then these countries could very well take the lead in becoming increasingly "futuristic" on their own, without having to look to the West for models and guidance.
