The answer to #1 is that I don't know. I wish I did. Some punishing of employers who knowingly (aye, the rub) hire illegals and some returning of them across the border would help. That silly interpretation of the 14th amendment that makes anybody born on this soil a citizen has got to go. But these will have have limited effect and noone should ever expect a miracle on this account. The easiest way to solve this is to (*gasp*) trade with Mexico to make their economy less anemic.
The answer to #2 is yes, but . . . After 9/11, the main concern is with people who scream "Death to America!" in Arabic and not those who whisper "¿Donde está el trabajo?" One of the problems with this is that overstaying the Visa is the easiest way of avoiding detection. Get a Visa, come to the US and get lost. How is anybody going to find you? Especially if somebody else is paying for you to live? The INS has life-and-death issues of a grand scale to deal with now and I am happy that they can devote any time at all to Mexican immigration.
But I do not have to come up with a solution. I am not the one who is calling switchboards to feel good about myself. I am not projecting a vast societal problem onto one bureaucrat with respect to one issue. You are the one who doesn't like what Hutchinson has done, so you are the one who has to tell him what to do. I have a bigger picture in mind and, believe it or not, I have better things to do than to get spammed by zealots who cannot see the forest for the trees.
Or the branches.
Or, for that matter, a single leaf.
The irony of it all, is that in the long term, the influx of Hispanics if controlled and limited to manageable numbers is a huge plus for the US. But the US should be able to choose who comes, and by the rules, and not allow the numbers to get out of hand. The chat about de facto amnesty has pushed the tipping point beyond the manageable to the unmanageable. That is my judgment call. And in this rather dangerous time, with so many who have come to really hate America (admittedly that is a different ethnic group or groups by and large but the point still obtains), I really want to know who is here and why. Is that too much to ask?
