I agree, although Canada and Australia are both resource based economies ... China and India will be using resources and will be trading in currencies that have value (they are not printing insane amounts of money to beat a dead horse).
The greatest concern is the social unrest North America will face and the spillover affect of the wealth transfer from the poor to rich the US is currently perpetrating.
I'll take a fluctuating currency for the relative safety of a country too far for the US to make theirs.
