Let's just allow that Graham is only saying that inventive people tend to cluster in one economic zone. It's an easy conclusion to anyone interested in the continued economic success of the United States that we should get as many of those people into the country as possible. Now if what we really want is to maximize inventiveness as a species / civilization... We probably don't want a monoculture of thought. We want inventive people in a diverse number of environments, all getting slightly different experiences and fresh angles on local and global problems. We could take a further leap and argue that we need to import diversity to solve the monoculture problem in the United States. But that's not what Graham's arguing.
