The main difference between Ukrainian refugees and what we usually get is that Ukrainians are, without exception, well-educated enough to start working right away, and not just in unskilled low-income jobs. Compare that with, say, Somalis with virtually no education, and not even able to sit through a class because they never got accustomed to as kids, then competing with natives for a very limited number of those low-income jobs. That's why Ukrainians get working permits straight away while we'd rather pay welfare for the Somalis until they're ready.

I don't know what it is with Seppos and making everything about race. There's actual fucking issues with integrating people from non-developed countries that are completely absent in the case of Ukraine. Ukraine may be piss-poor, yes, but its fundamentals are solid, quite a bit better than Romania and Bulgaria even I'd say and those are EU members.

EDIT: While PISA numbers are to be taken with a whole salt shaker as measuring good education is notoriously difficult (see "teach the test") Ukraine outranks Greece across the disciplines. More or less head-to head with Italy.
