I suspect the Amero will be introduced before the dollar completely tanks.
Some of the articles I have read imply that a currency crisis is being created intentionally so the sheeple in US/Canada/Mexico will accept the Amero as the solution to the problem.

A standard tactic in sales and government is to make the customer or citizen aware of a ‘problem’ and then present the solution to the problem
problem: currency crisis / dollar losing value
solution: Amero
Most customers/citizens won’t realize that they have been manipulated.

The Amero will be just another fiat currency for the elites to debase – ultimately it will be added to the list of dead fiat currencies along with the US dollar.
