The short answer to that is yes. I think there is a mobility, but you're very right in terms of citing the fact that it's not just one individual who's moving; it generally is families, and uprooting when you are still thinking that it's not likely a more permanent or sustainable change, that it's just a condition of the economy for right now.... What happens in three, four, or five years if the economy slows down and they've moved their family? Have they made the right decision? It's a very massive change.
