Multiply the relatively insignificant 'single case' by thousands, tens of thousands, hundreds of thousands and suddenly the numbers are very significant. Not only that, refuge, once granted can't just be revoked if/when things get tough economically and/or socially, so any problems which arise after the event are not going away any time soon. I fully expect ethnic tensions to increase in Greece with the economy there tanking at the very time migrants numbers are peaking with the accompanying demands on their economy. It's really not rocket science for anyone who can see beyond the end of their nose.
