califchris,
Just about every expert I've heard or read say that it is impossible, and therefore a waste of time, resources, and money to try to close a 2,000 mile long border that runs through deserts, mountains, and at least two major rivers.
There are 250 million LEGAL crossings of the border a year and about 500,000 ILLEGAL crossings. Countless billions of dollars in revenue depend on open borders, particularly with so many so-called American companies moving their manufacturing plants and agricultural operations south of the border.
In fact, there is some evidence that this episode of swine flu traces back to an American pig farm located in Mexico that has been the subject of countless complaints by locals for environmental violations.
So, if we were somehow to miraculously stop illegal immigration across the border, we will only stop two-tenths of one percent of the people crossing the border. The other 99.8% are legal crossings.
And, if we were somehow to miraculously close the entire border, many billions of dollars will be lost and many thousands, perhaps hundreds of thousands of both Americans and Mexicans will endure financial catastrophes and possibly ruin.
Please try to think through the deeper consequences of the off-the-wall ravings that Fox News and other xenophobic racists and nativists are heaping upon us to play on our fears and hatreds.
