To be fair, the polish imigration however didn't come in waves and cause potential economical collapse.

(and that's coming from somebody who's supporting of all the refugee's in europe).

I'm okay with escaping war, however at the moment it is getting out of hand and needs to be controlled. A large part of the imigrants aren't even Syrian and there's a lot of money laundering and other illegal smuggling behind it. On top of that, you need work-force and people to be integrated into society. If you create too much cultural diversity the very grounds of your own culture and society will collapse and it this situation needs to be managed accordingly.
