The fact that the majority of refugees arriving to Europe these days seem to be pushing to get to Germany, Britain or Scandanavia despite being able to "survive" in Turkey, Greece or Italy seems to refute your point a little.
I don't see that it does, really. If Turkey gave citizenship to these refugees, and just allowed them to start their lives, they would perhaps have continued to stay there. Maybe I should have used a better word. They left their homeland to escape terrible conditions, but their conditions in camps in Turkey or Greece aren't very good either. They are trying to get back a semblance of normal life, which Germany seems to promise them.
