Let's not overlook the possibilities here, the chance for vigorous and creative entrepreneurship. Certainly, the ramifications of deporting a whole lot of parents of children is daunting, but surely there is a way for private enterprise to create value, to monetize the resources of vast numbers of parentless children.
Recent experiments in privately owned juvenile detention centers might well provide a viable business model! Little hands need to be kept busy, this is common sense, and the advantages in early preparation for the labor market are clear. Surely we don't want to raise a generation of moochers dependent upon the "nanny state"! We already have long-standing traditions of employment in agriculture for such people, though it is hindered by poor messaging. "Stoop labor" becomes "earth oriented", for instance. "Child labor" becomes "pre-adult work training", "juvenile detention" to "youth opportunity centers"...
