See comments below re: Jorge Borjas and Adam Davidson.  Note, too, that in Feb. 2014, Aaron Blake of WaPo stated: "The head of the Heritage Foundation's political arm said Monday that the comprehensive immigration bill passed in the Senate last year is the result of "corporate cronyism" and blamed another group that often aligns with Republicans, the Chamber of Commerce."  The Chamber of Commerce, mainly Republican, is a main player in corporate cronyism.  

Opposed to corporate cronyism --- and to illegal immigration --- is Cornell University labor economist Vernon Briggs, Jr., who, in his briefing to the U.S. Commission on Civil Rights regarding "The Impact of Illegal Immigration on the Wages and Employment Opportunities of Black Workers," stated that "no issue has negatively-affected the economic well-being of African Americans more‖ than immigration. * * *  Dr. Briggs viewed such losses as a denial of basic civil rights and economic opportunity."
