Do you have a source for that? That is interesting.
What about restaurant and hotel workers? Landscapers? etc...
you know, i read about the study here on fr. i think. i seem to recall that there were at least a couple threads appertaining thereto, but i couldn't find them after a few searches. so i went to google and tried and failed again. hm. can somebody help me? or did i have a particularly realistic dream? i did, however, find the following page, which makes much the same points as did i, with the exception that it being a lefty source, their answer is to raise farm wages via government mandate (minimum wage, etc.), where i myself, and many on this forum, too, i believe, would rely on market forces (and enforcement of our immigration laws) to do the trick. but, for what it's worth: http://www.therationalradical.com/documents/farm_workers.htm
