What the EU thinks it will get: an American success story of a melting pot.
What it will get: a multicultural garbage can like Canada with communities that don't integrate and zero identifying with the host country.
I'm not that well versed in Canada, but from my understanding there doesn't exist the sort of enclave societies that gets sealed off from the rest of country like it does in Europe; the banlieues of Paris or the suburbs of Stockholm. There is no surprise to see no adaption growing up in such an environment. You have no incitament, you could say it's on the immigrants to change, but if you see/feel you won't be awarded for your efforts then what would be the reason?
The social mobility is low and crime high in these suburbs, making up a completely foreign place to that just a few km's away. It's just not good in any way shape of form. People who promote it are completely delusional useful idiots. Much of it comes down to terrible urban planning, creating cheap concrete housing-block areas outside of city centres. It was a terrible idea from the beginning, even when natives were living in them the social ostracization was high. There is no political will to deal with the situation because being walled off, never seen, you can pretend these areas doesn't exist really, only useful as a place to fish votes when the times comes around.
It's especially sad for the generations of young girls in these areas that get shut in and forgotten about. When you speak up about this issue in Sweden, even if you're a women who grew up in that enviroment you get hounded and ostracized by the delusional Swedish upper-middle class, who are completely fine to pretend no problems exist. The paralyzation on these issues makes you astounded. Like some Orwellian nightmare.
The situation is a consequense of terrible politics just as much as it is people coming from a "terrible" culture. I'm no cultural relativist, many immigrants comes from patriachal countries and brutalised war-zones, they won't automatically share western values as soon as they cross a border. Western "human rights" isn't some sort of immanent idea existing deep in every human being, it's taught. Sadly it's often western countries behind the brutalisation of these countires, especially the middle-east. The presence of a pre-existing animosity isn't some fantasy. For good reasons in some ways, thanks America btw.
