It's called "insourcing."
This is the global corporate agenda at work. The corporates control the government, they control the border. If they wanted illegal immigration stopped, it would stop tomorrow. Instead, corporate profits remain king. In their pursuit of ever growing profit margins, any American job that cannot be outsourced (to cut wages paid), will be insourced. Mexicans are a cheap (low wage) labor pool easily insourced and exploited for higher corporate profits.
