Australians speak English, so that's somewhere I also consider since I'd adapt more easily I think. The only foreign country I've been to was Canada for a couple of weeks when I was 16 or so. If I did win a lottery, I'd probably relocate to another country just to see more of the world.
I'm sure quite a few of us might consider emmigrating if we won big on a Lottery, I mean I would consider it Canada, New Zealand or Australia do sound nice. But there is a difference between visting and living in another country. After all there is so much to consider, uprooting your family if you have one, leaving your friends/other family behind etc.. Are we moving because we thing the grass is greener?
It's very difficult for Americans to emigrate to Commonwealth countries. And many people don't adapt for lots of reasons. Australia and NZ can seem like country towns if you've lived in big cities in the US or with Europe at your doorstep.
Not to discourage you all. We just had the most glorious summer..
