Immigration and the Myth of Plummeting Wages

One of the main justifications that people use in their effort to oppose immigration is that it pushes wages down. The only problem here is that it largely isn't true. I cite specifically the research of Harvard economist (and staunch immigration OPPONENT), George Borjas. According to Professor Borjas, the long term effect of immigration on wages overall is ZERO, and even the long-term effect on low-skilled individuals/high school dropouts is only about 4.8%. The "solution" here seems to me to be one of better training the American work-force and NOT trying to keep hard-working and law abiding Latin-Americans out of the damned country (http://econlog.econlib.org/archives/2007/03/borjas_wages_an.html).
