Contrary to the Buchanan/Tancredo sloganeering, we do not have open borders. Border jumping can be very difficult, dangerous and expensive with no guarantee of success.
Once here there is no guarantee of work. There is the constant threat of being caught. And there is always the yearning for home and family.
But as long as our need for immigrant labor is great enough and their desperation to support their families strong enough they will find the way to get here.
If we ever decide that there are too many illegal immigrant laborers all we have to do is start busting employers. But you and I both know that no mayor or governor wants to bust taxpaying businesses.
I propose that the federal government assemble a special ICE force to bust employers of illegals and then ask Congress which members would like them to come into their district first. Do you think Tancredo would ask them to bust the employers in his district?
People who "immigrate" to America still do want to become citizens, but guest workers only want to work here and go back to Mexico or India or wherever. What's wrong with that? Everyone benefits.
Where do we draw the line? How many legal immigrants should we let in and why? We let in something like 2 million every year right now. Something like 98% of the entire world is worse off than Mexico. Why should Mexico come to the front of the line? That 2 million we let in is just a small percentage of the annual birthrate of all of the nations worse off than Mexico. There's no way we can help any of these impoverished nations by taking in everyone who wants to emigrate. And what kind of people do we want here? Poor, undeducated and unskilled? No. Skilled and educated? Sure, we want only the best and brightest to come in. They're better but it does their home country no favors if we take away their best and brightest. There's a major problem in Mexico that all of their young men are abandoning their towns to come north. This has left entire towns devoid of all but old men. And these towns are primarily farming towns and now the elderly have to try to work the fields. The mayor of town came back from Mexico a few months ago and reported just that.
