Conservative farmer friends made a point of telling me that without latino laborers their farms would have "gone under" long ago.
Here is a pertinent excerpt from a 2010 "Voice of America" article: "With U.S. unemployment near 10 percent, many believe illegal immigrants are taking jobs from Americans. But when the United Farm Workers union launched a campaign offering to connect unemployed people to farm jobs, only three people accepted -- out of thousands of inquiries." http://www.voanews.com/a/us-farmers-depend-on-illegal-immigrants-100541644/162082.html
A final note...
A North Carolina judge friend, whose family has worked the land since the 1600s, confided: "The next time there's an economic boom in the United States, we will BEG Hispanic laborers to come back - and the economic powers that be will not care if they're legal or illegal."
