I suspect that there are actually a couple of other reasons why muslims are better integrated into the US than Europe: a) It's more geographically remote from Islamic countries hence you have fewer unskilled immigrants turning up. b) American has less in the way of welfare so immigrants (and their children) have to get jobs. Working with fellow citizens makes you realise that you have something in common with them and encourages integration.
