Now that's where Aussies tend to differ....we don't expound the virtues of Oz over all other countries as 'the finest country on Earth'.....usually, when pushed, we'll just say we wouldn't want to live anywhere else....
I've been to a few countries....that was 30 years ago....and it was as an Architecture tour, so wasn't for very long.....therefore my actual KNOWLEDGE of life and living conditions, etc in other countries is second-hand, at best, so therefore coloured by external opinion/prejudice.
My guess is thet taking into account issues such as pitiful gun-control, privatizing of medical assistance/benefits, etc, I may just want to tend to put the USA down a notch.
Yes, Australia under Imperial rule kinda trashed the rights of the Aboriginals...so a mark down to us...but we were still under the wing of the UK, back then...
Then of course, there's the problem of the '500 Nations'....[or lack of]...but that's down to the Spanish and English and French, I guess.....and John Wayne, of course..
I'm sure there are possibly 'better' countries on this planet than any of these mentioned....but if it's all about penis-envy then the great old US of A has the biggest of almost everything.....except Ayres Rock, of course...
