Canada is really easy. Denmark is pretty good, so is Australia/New Zealand. Asian countries love high quality labor. Other than that, try investing or marrying into the country :)
This is why BC and Alberta were thriving when the Canadian dollar was worth more than the US dollar and the price of oil was sky-high, while Ontario was suffering. That said, I'm not sure of the larger implications to the Canadian economy as a whole if the US tanks. It may be simple to move to trade with China, though it may not.
And that is after you get here.
