You breed 'em, you feed 'em! Personal responsibility seems to be a thing of the past where some of these "Families" are concerned. Added to that there are quite a few who have multiple kids from multiple partners, why the hell should those who go grafting to care for their own families have to stump up (via their taxes) for the lazy & feckless?
And we've not even started talking about the rest of the world who've come to good old Blighty, bringing their brood, the sick, lame & lazy, all with their hands out & haven't paid a penny in & are never likely to either!
