Yes that would be a total surprise wouldn't it, economic migrants trying it on, forged papers readily available to anyone who can pay, but don't worry there is no significant risk...
Let's be honest, few people would prefer to spend months even years in camps like that only to be sent home some time down the line to a large pile of ruins, no jobs and quite possibly decades of instability, resentment and worse. If we can understand that surely we can understand the hugely powerful instincts which are at work when large numbers of desperate people are on the move. If the EU accepts that it can't give refuge to all the world's needy, at what point are they going to stop trying to do so and what measures are they going to take to stem the flow they've helped to create? There doesn't appear to be a Plan A let alone a Plan B.
