Funny that some of you think things in Turkey are all well and good just because of monetary compensation.
Infrastructures in cities are by and large unable to sustain the influx of so many refugees in so little time, and civil unrest (due to racism and other prejudice) has been escalating for years, for many reasons like people feeling resentment over not receiving governmental help they need while the refugees do, or schools having to welcome so many new refugee students at once that proper education becomes practically impossible. Any country would have trouble welcoming so many people who don't speak the local language and who need an incredible amount of monetary/otherwise help.
This is part of the reason why Erdogan lost Istanbul last year.
Turkey has already been suffering the consequences of bearing the brunt of so many refugees as a developing country with an economy in almost-perpetual crisis. All the pearl-clutching about what'll happen to EU countries is pretty humorous to see when none of you gave much of a shit about all of it happening in Turkey.
Erdoğan wasn't housing these people out of kindness or humanitarianism, true, but Turkey itself as a society has been panting under this logistical, economical and social burden for ages, and Europe only enabled it by using its own good ol' xenophobia to buy some time.
Europe made is bed and will lie in it.
I am not happy about this, myself. But it is what it is.
