Why is this not happening to other Muslim communities, like Pakistanis and Arabs?

Arabs are practically indistinguishable from Somalis in their dysfunction here in Scandinavia. And last i heard Pakistanis weren't doing so hot either in the UK. These aren't model communities in Europe, although they are doing better in the Americas.
