AFP: Some 700 million people worldwide, or more than all the adults of North and South America combined, think the grass is greener on the other side of the fence and want to permanently move to another country, a poll showed Tuesday. The most popular destination was the United States, where nearly a quarter of the 700 million -- around 165 million people -- said they would like to settle. In joint second were Britain, Canada and France, each being named as the preferred destination of around 45 million people. Thirty-five million said they would go to Spain, 30 million to Saudi Arabia, and 25 million each to Australia or Germany.
