It kind of reinforces the fact that the distinction between "immigrants" and "expats" is largely income-based. It reminds me of the great animated film "Persepolis". When discussing leaving Iran during the Iran-Iraq war, the father of the main character replies to his wife "So that you can be a housemaid and me a taxi driver?" (they're both middle-class). If they left, they would be become immigrants. On the other hand, somebody in the western world from the middle-class migrating from one location to the other would expect to retain their social status and find an equivalent job. This kind of difference is pretty sad.
