At this point in time, it is difficult to imagine a single global currency as a viable alternative to the existing mix of fixed and floating exchange rates, though regional currency unions are likely to continue to grow. However, the ultimate size of these “currency unions” has yet to be determined, consistent with those who see a future in the GLOBALL. Not surprisingly, international surveys generally suggest that outside of the US, much of the world is not as averse to “international systems” that subordinate nations (save for Britain recently as well as others), whereas those in the US have difficulty with “international systems” unless we are at the center of the system (e.g., the US dollar as the GLOBALL!).  You can argue that these results have to do with the relative costs and benefits as well as with differences in political views on the nature and power of government systems and institutions, which brings us to our next course related investments topic on hedge funds.
