Something to do with financial hubs and the Sea?

Over the last 2 years, I've been fortunate to spend time in Bombay,Singapore,Hong Kong and London. All these cities are reasonable nerve centres of financial activity and are along the sea. I see that each of these cities have a similar character in the sense that, the services are excellent for the common man in infrastructure, a relatively advanced society, a cosmopolitan culture and cities where people rise up in life the hard way. I dont know if any of what I point is connected, but this was just a thought. I seem to have developed a great deal of affinity with each of these cities. Throw me in these cities, and I would probably enjoy my way around the city and with people from the city.

Any similar thoughts?
