If I had to constantly compare NZ with some UK/Europe countries, I would go absolutely nuts and totally depressed!
I could have moved to Norway without immigrating. My sister lived there for 12 years, came back to SA for 4, went back for 1 year. She is now in Asia. The country is clean, it is a socialist country so the government really looks after its people, but they have so many problems now with the refugees that they welcomed into the country. The muslims want to practice their own law, when the prime minister refused, they actually threw a bomb into her house, setting it alight, one night when she and her family were all asleep. She has kids. It is incredibly expensive. There are so many people on the dole. When I was there, there were other racial issues which freaked me out a bit. I would never go and live there. They are completely different from us. And Norway is No. 1.
Have a good friend from the UK. She is looking for a better country to live in. With her husband, child and dog, they went to Portugal, Spain and France for 1 year. Living with with people, working, etc. They discovered that life is not so rosy as your dreams, in these foreign places. They thought it would be France for them, but have now chosen Portugal.
As I often say, we are all so different. And these places are not all cool. IT is what you want out of life that is the deciding factor.
Like Rockhopper, I am quite happy in my little piece of paradise here.
