> Collapse... Collapse... Collapse... Nowhere in my comment did I say that word. Why such a bleak outlook? > To assume that the world is as isolated as it was when the Spanish peseta collapsed as it is right now is absurd. I'm not sure which history book you're reading, but your statement has no historical basis. Isolation didn't cause the peseta to "collapse", economic cooperation caused it to MERGE into the Euro. That would seemingly display the exact opposite of "isolation", wouldn't it? I'm pretty sure Europe didn't collapse into an apocalyptic wasteland in 1999 when the Euro started as a currency. The Euro would have sounded preposterous in 1990, the year in which the reunification of Germany took place. 9 Years later the Euro started, 2 years after that Germany was the first to eliminate their own national currency as legal tender. What stops the USD from merging with the CAD and/or MXN other than a lack of imagination, or a recency bias?
