There are legal ways to bring in cheap labor from overseas to do brutal work for low wages.
Immigration attorneys typically make at least $20,000 per immigrant (because the application process is labor-intensive) who then work for close to minimum wage.
According to Wikipedia: “ProjectUSA is an immigration reduction political advocacy group. According to the group’s website, it is “a nonprofit social advocacy group based in Washington, DC and dedicated to raising public debate about the important issue of mass immigration. We advocate ending illegal immigration, reducing legal immigration to traditional, sustainable levels, and a ten year time-out while the country reassesses immigration in terms of the long-term consequences of present policy.”"
I first picked up the Agriprocessors story in May, 2004.
