I agree with Olecapt. The anti-immigration guys are selling a fantasy. And the road to that fantasy is paved with unitended consequences. For example, the E-Verify program cited in the article is frought with errors. According to a new report from the Cato Institute, a free-market think-tank:

"Then we must consider the error rate in federal government databases. In December 2006, the SSA’s Office of the Inspector General estimated that the agency’s “Numident” file—the data against which Basic Pilot checks worker information—has an error rate of 4.1 percent. Every error resulted in Basic Pilot’s providing incorrect results. At that rate, 1 in every 25 new hires would receive a tentative nonconfirmation. At 55 million new hires each year, this rate produces about 11,000 tentative nonconfirmations per workday in the United States—a little more than 25 people per congressional district, each day of the working week, all year long."
