Gotta do it somewhere..
Umm, we may have a global economy but with vested national interests. Whoever could have thought that something like this might happen? Oh my..
Anything that focuses on short-term isolated results (think national borders, corporations, quarterly statements etc.) will cause interesting situations like these, where the supply-and-demand chain will collapse if there are no rules to restrict monopolies. And there are on national levels, but not international, and again, with vested "individual" interests in "groups", an outcome for the greater good is decidedly not a given (think COP15 in Denmark..)
