Same. I lived in Japan, Taiwan, and mainland China for about 10 years, and I only came back with my wife because we want to buy a house here in the States. After that, we're going back to Japan and China.
The US is so far behind in public infrastructure (trains, pedestrian, cycling, etc) that I can't see the States being a good place NOW, much less the next fifty years.
Why do you want to buy a house in the United States that you never plan to live in?
