First, I apologize if I've misinterpreted your message here. You may be selling vacation travel to other countries a little short. I can only speak for my own travels over many years, but each trip to a different region (even within the U.S.) has given me a renewed appreciation for life. Many of these trips have also dispelled my previously held beliefs about a particular country or culture. I find value in those experiences. You shouldn't think less of those who don't take up a new life in a different culture. Life has many paths and every path isn't appropriate for every person.
