Usually in Europe, the problems with immigration (and yes, they are full of them) are because the European countries themselves do not want to integrate them. Sometimes the comments suggest that the EU is spending billions on welcoming and accommodating Muslims - shit they are spending, not money. It has always been the priority of EU states to push out newcomers as quickly as possible, to make it as difficult as possible for them to enter legally, to put up every possible barrier, and to push those who have slipped through as far away from their eyes as possible. Let them live in their own communities, in their own ghettos, whether they want to integrate or not, so that they do not contaminate our white Europe. Half of the immigrants work in slavery - in the same sense as many Lithuanians did in the West 20 years ago. In Sweden or Germany, kebabs are cheap because companies secretly employ immigrants, pay their wages in envelopes, keep them in slave-like conditions, and thus cut costs. And if you look past that, of course there will be crime and gangs and all the rest of it, because you can't do otherwise.
In Lithuania in the 90s, crime was also huge because of the same desperation. Lithuanians, Latvians, Poles in Western Europe (and 100 years ago in the USA) were also confined to gated communities, and were also considered criminals, bandits, etc., who polluted the local society (after all, until about the 20th century, we were not really considered white, like the Slavs, until about the 20th century

) How many mafiosi there were in Norway, how many problems we had with Lithuanian alcoholic parents in Norway, whose children had to be taken away from them by the authorities. Well, we won't say that Lithuanians haven't tried to integrate, or that they are some kind of scum by nature.
So, in a word, it is a question of who is to blame for this integration crisis.
