For you, mate.
I do wish to belabour the point. The essential idea is this: the principal comparative of big cities is the facilitation of diverse face-to-face contacts and the brining together of people, further buttressed by scale economies in the provision air travel, resulting in ‘hub’ cities that offer a greater diversity of potential contacts and are globally the most accessible. The name of the game is people: the transport cost of people is the essential variable, where the principal cost is the opportunity cost of time. One of the ironies of modern economic growth is that the opportunity cost of time is increasing; notably for knowledge and creative-type workers, be they managers, researchers, computer geeks or entertainers.
