The dollar is the first thing seperating the first world from the third world. There are enough differences in the infrustructure, education system, and various other aspects of the cultures to seperate the two "worlds" generically; stereotypes can be made on any thing.
And with the world descending into choas, what will be the first dam to break? It will be the dollar. The wall was thin, and paper is not the best to withstand the elements, except when written on exclusively.
