With the exception of either a geographic advantage (i.e. access to ports, proximity to other trading partners, industrial clustering - Hollywood,Silicon Valley, etc) or political creations (Singapore, Israel, etc), why does economic wealth tend to cluster in less pleasant climates? In general, it seems the closer you get to the equator, the lower the economic prospects.
Northern Europe vs. Southern Europe? Even more visibly, northern Italy or Spain compared to their southern counterparts?
Why have cities such as Chicago, New York, Boston managed to create a more diverse economies than that of Oklahoma City or Mobile, Alabama?
Do milder climates somehow promote productivity, ingenuity and creativity? Clearly, year-round agricultural activity was never an option, thus leaving people to devise alternate means of economic subsistence.
