There is no "Best" country in my opinion.
Anybody with an open mind may realise that whereever they go there are good and bad points about that place. Even paradise would get boring after a while. Humans subscribe to the "grass is always greener" theory.
I love Aruba but eventually I would want some cold wet weather for a change....
Here in England for instance the weather changes are good, snow in winter, sunshine in summer, green fields and rain. Trouble with that is the seasons change too quickly to get used to anything. Our taxation system is ridiculously high but we don't have to pay for health care insurance either. Tax on gasoline is about 80% as well but then again, if it wasn't there would be too many cars on this little island for anybody to get anywhere.
If I had a choice, based on experience and places I've been I would live in maybe Majorca, Aruba or Monaco. Having said that I love Miami and London too. But the flip side is I still have to experience New Zealand and Australia, Hong Kong and Japan. Unless you have visited every place on the face of the earth you can't really make a defined choice.
I will say I believe the "general" belief within America is it is the "best" place in the world, which I find rather funny and it's a kind of cultural difference the rest of the world mock America for, an "in joke" the rest of the world share.
Having said that my own opinion is the "general, i.e. majority " population of America are arrogant, ignorant and self indulgent people.
Christy, I remember you saying how rude the crowds were to you at the US Mac gigs yet the European audiences were far more polite and friendly. I'm just using this as a basic example.
But, the majority of Ledgies here, and quite a few Americans I have met seem to be in the minority catagory (I'm not saying Democrat!) which means you are intelligent open minded INDIVIDUALS. Sorry if I've offended anybody with the last remark!
Just my thoughts...
