Hmm, I don't think its the same thing though. The US has multiple stock exchanges and many different cities hyper-specializing in different things (e.g. SF- Tech, Chicago-Commodities, NYC-Finance, Houston-Energy). The country itself is a powerful economic engine with all that land and close to 300 million people. In comparison: the only reason Singapore did so well because economic activity in APAC needed to be directed from an English speaking country in the region which was stable and had a well established corporate laws/governance. Now that other countries are catching up, Singapore is rapidly losing that advantage.
