Economist Tyler Cowen [Email him]has an Op-Ed in the New York Times called How Immigrants Create More Jobs October 30, 2010.

It's based on a study called "Immigration, Offshoring and American Jobs,"? by Giovanni Peri [Email him]of the University of California, Davis, and two others, one of whom is a Professore at an Italian University, which means that, in effect, this offshoring study was partly offshored.

For George Borjas' comments on Peri's work, see here.

I am prepared to admit that immigrants do create jobs for a number of people:

• Border Guards
• Police Officers
• Prison Guards
• Social Workers
• Teachers
• Doctors And Nurses
• Funeral Directors

But now, of course, because the scale of the immigrant invasion, those jobs require knowledge of Spanish, which means that the jobs will go to immigrants.

And in terms of the free market, immigrant entrepreneurs frequently create jobs for other immigrants, usually their wives' relatives, in motels and convenience stores. What they do not do is create more jobs than they take, or provide a net benefit to the American nation.
