Yes, and if this map is true it'd also be interesting because it counters the common argument that our countries aren't welcoming enough to the "job creators", but i wouldn't know how to explain that, e.g., China lets this happen, the full implications, and a lot of other things not told in that simple map.
It seems at first view like another illustration of the unfairness of neoliberalism(, not only a brain drain, but a capital drain as well).
