The economic refugees are from all over - Ghana, Pakistan, Afghanistan, Nigeria, and so on. Presumably (and I say this with an incredible assumption because it seems that Europe is really just acting suicidal right now) all the people from these countries with some very serious exceptions would be returned (I would imagine someone from Pakistan who could show he/she was falsely accused of burning a Qur'an and barely escaped alive would have a case for asylum).
With respect to refugees from war zones, the only sane bare minimum policy given the overwhelming numbers is (1) no, you can't invite relatives to join you and (2) you only get a temporary right to stay until the war's over, with no automatic right to transition to permanent residency or citizenship.
Even if Europe does that, it will still have more people than it can realistically cope with. So yes, Saudi Arabia and the Gulf States should do more. They can take people. If Saudi Arabia just accepted 100,000, and the Gulf States among them another 100,000, between that and deportation Europe could START to deal with the influx. Sending some others back to camps in Turkey, Jordan and Lebanon is problematic but probably has to be done.
But seriously, these naive people like Jens are taking an easy stand right now, but when the economic effects of this influx make themselves known, how happy will everyone be? Endemic poverty among the refugees can only make the crime situation worse, and high unemployment is set to continue as the Eurozone is slipping into recession again. This whole situation is just like a huge ISIS time bomb.
ἡ δὲ κἀκ τριῶν τρυπημάτων ἐργαζομένη ἐνεκάλει τῇ φύσει, δυσφορουμένη, ὅτι δὴ μὴ καὶ τοὺς τιτθοὺς αὐτῇ εὐρύτερον ἢ νῦν εἰσι τρυπώη, ὅπως καὶ ἄλλην ἐνταῦθα μίξιν ἐπιτεχνᾶσθαι δυνατὴ εἴη. – Procopius
