> A kid, even at 17, is much less autonomous, will have an educator or foster family, will go to school, etc, they are going to be 'enrolled' much more actively into society.
That's nice in theory, but it doesn't actually bear out in practice. As one example, according to [0], even second or third generations fail to integrate (with disastrous results), and AFAIK that's the rule rather than the exception (though there are quite a few exceptions, more in the UK, less in mainland Europe). It's not enough if even 50% integrate successfully when the number of immigrants is so high.
