I can understand economic migrants from poorer countries working in a wealthier country and sending money home to help their family build a better life but people from wealthy countries going anywhere else just doesn't add up in my book, except, perhaps, when they are young free and single as Brendan mentioned. Might be great to be the pioneer and conquer far-flung lands, but when your family comes along, how about staying at home. I mean, there are only so many temples you can see in one lifetime. As Blake said, you can see the universe in a blade of grass. And, sorry, I think it basically unfair to deny grandparents and other relatives simply to satisfy your own internal wanderlust.
