Haha, excuse me for not jumping to that conclusion straight away, I have never heard the ability to live in the bush being used as an argument for another country in a discussion about Australia!
Also first link in Google: rough it - to live in a way that is simple and not very comfortable
Don't pretend search engines deliver the same content to everyone
I'm not suggesting you jump to conclusions. I'm suggesting you do basic research when you don't understand an expression. By the time you skim the first page of results, whether or not it's the same as my first page of results, you should have a clear idea what the idiom means.
> "an argument for another country in a discussion about Australia!"
The immediate discussion was about whether there were arguments for living in America, not whether there were arguments against living in Australia. The US has a lot of things going for it; whether or not some of those things also apply elsewhere isn't really relevant.
