Truth is, most migrants end up benefiting their new country despite a general hostility towards them. It's always been like that, even in XIX century US. So there is no hypocrisy really: we are not letting them in "because they help with taxes", that's a secondary side-effect that we are forced to emphasize in modern debate only because we have to fight naturally-xenophobic elements in our societies.
Can we put (dubious in my opinion) benefits from migrants against girls (including teenage and children) raped by said migrants and weight it up? How much money does one child rape cost?
And this is not unique, in the UK they busted like a dozen of underage brothels any of which had dozens of underage girls abducted, beaten and made prostitute. Brothels of course run by muslim immigrants.
