When it comes to assimilating new arrivals, Europe could learn a thing or two from America, which has a better record in this regard. It is not “culturally imperialist” to teach migrants that they must respect both the law and local norms such as tolerance and sexual equality. And it is essential to make it as easy as possible for them to work. This serves an economic purpose: young foreign workers more than pay their way and can help solve the problem of an ageing Europe. It also serves a cultural one: immigrants who work assimilate far more quickly than those who are forced to sit around in ghettos. In the long run most children of migrants will adopt core European values, but the short run matters too.
