Welcome the Amero!
The Gubbamint won't have to force it on us, we will gleefully convert to save our investments.
I don't see the Amero happening. First of all, what good does it do the US gubbermint to let Mexico and Canada in on the reserve currency game? If it was the only thing that could save us as the reserve currency I can see them trying, but do you really think the rest of the world is gonna be impressed by a US currency strengthened by Canada and Mexico?
I don't. They'll go running to the Euro or the Yen.
