Mickey Kaus at left of center Slate has evidently been reading Viewpoint on how to handle the illegal alien problem. Well, at least his solution is similar to ours:
Two consequences follow:
1) Any system of employer-based enforcment should probably be applied only to new hires, not existing employees. Existing illegal employees wouldn't be "legalized," but they wouldn't be subjected to non-charade, computerized checks of their social security cards, for example. They'd just continue working as before.
2) A border wall or fence, widely denounced as the crude favored scheme of the meanest, yahoo, Know-Nothing elements of the Republican House, is in fact the most compassionate enforcement solution. A wall intrinsically blocks only new entrants. It's a physical grandfather clause! It leaves current illegals where they are.
Would this "grandfathered" solution--leaving existing illegals working in their current jobs--amount to legalization or amnesty, and thus act as an incentive to would-be illegals still on the other side of the border? I don't think so, because the benefit of already being here--being left alone--would only be valuable to the extent border controls were effective. If the border remained porous, existing "grandfathered" illegal workers would only have obtained the ability to avoid border controls that were meaningless anyway. If the border controls weren't meaningless, would-be illegals now in Latin America and elsewhere would have an incentive to sneak into the country and work--in the hope of being grandfathered-in later--but by the same token they'd have less ability to do so. (They'd have to get over a wall and get around an effective system of employer-based document verification.)
Also, the existing, left-alone "grandfathered" illegal workers a) still wouldn't be legal and b) couldn't change jobs without subjecting themselves to the non-phony, computerized document check. Eventually, as they left those jobs, they'd be put to the same choice (self-deport, or work underground, etc.) as would have been put to them if they'd never been "grandfathered." But the process would be drawn out over years. And by then, there might be a guest worker program for which they could qualify (perhaps by returning home and waiting at the end of the line, perhaps more easily).
Let's hear it for a "mean, Yahoo, Know-Nothing" solution to a serious problem.
Of course, strict enforcement of the border would require that politicians be able to withstand allegations of racism and sundry other mean epithets. This reality drains away any hope we might have had that an effective border security system (i.e. a fence) would ever be implemented. Politicians, after all, are not distinguished by their willingness to risk public obloquy to defend a principle.
