True. I am from another welfare state dealing with the same problems and discussions (The Netherlands). But it needs to be said that the system was grossly misused by native Dutch as well. Laws have been tightened since the beginning of this century, but some groups continue to be resourceful in exploiting the system.
Also interesting is that the anti-immigrant party is most popular in a low-immigrant, economically weak region (Limburg). It's highly paradoxical that people in regions that rely a lot on social welfare accuse others of bankrupting the state (immigrants, The European Union, and state officials are popular targets).
