Turkey has spent more than $30 billion on refugees and was already host to 2 million refugees in 2015 (i.e. before the deal) [1]. So, no, that deal hasn't brought any meaningful change.
I was aware. But the costs of accommodating refugees are more than just financial. The social cost is much bigger. I think it's fair that Turkey is looking for a longer-term solution for asylum seekers, not simply taking money and feeding them.
Are you aware that this is wholly down to a deal between the EU and Turkey which includes, amongst others, payments of about 6bn EUR to Turkey?
