Bullshit.
The percentage of undocumented latinos (that's what you meant) in those areas is not appreciably higher than anywhere else.
I'm getting really tired of the latino bashing that goes on in our society. If the jobs weren't here, they wouldn't come. Why not put more pressure on the business community that hires these people?
Even in racist Modoc County where I used to live, most of the field workers are undocumented, and the big farmers get away with treating the workers like shit. The community hates the field workers, but without the money they put into the local economy, that place would dry up and blow away. The local white people are either rich or on some bullshit disability or on welfare and won't take the field jobs. I trusted the Mexicanos more that the white people up there because I knew they wouldn't rip me off. They are hard working REAL people, much like the white immigrants that came to California during the Dust Bowl era.
