::I think there should be more on the Canadian aspect of critism of a proposed united currency. As the article stands, it is decidedly American in terms of the arguments against it. In some quarters, it seems that it is seen as a "given" that Canada and Mexico would leap at the chance to piggy-back on the US dollar, when for reasons such as you state that is not the case at all. In fact, there is a lot of resistance to the notion in Canada that we should join the US dollar or create an Amero-type currency. It IS more welcomed, the concept, in Quebec, but I doubt most Canadians would favour the idea, peso included or not.
