I don't know if 9/11 is going to change that fact either. Last April, China forced down one of our planes in international airspace, kept the crew hostage for ten days, forced us to chop up and crate out the plane, and then gave us a "bill" for their expenses. Our response? Grease the skids for their entrance into the WTO. It's the same with immigration: illegal "guest workers" will continue to flow over our southern border, take jobs and government benefits, commit crimes, breed, vote, and eventually govern discrete regions of the US. Young men with ghastly staring eyes from Saudi Arabia and other "moderate" Arab states will continue to get visas of some kind or other---maybe not "student visas" any more---to come to the US and "study" our infrastructure and technology---or maybe they'll just sneak over the Mexican or Canadian border.
You'll see---all this talk about immigration restrictions and reform will come to virtually nothing. With our political and business elites, the "bottom line" is more important than our bottoms any day of the week.
