"As the economy boomed in the mid-
2000s, many immigrants in southern California’s border country
spurned field work in favor of construction and food-service
jobs. Then they stopped coming to U.S. farms altogether. So Larry Cox, who farms lettuce, cantaloupes and onions on
3,500 acres in Imperial County, California, shifted more
production south of the border, where the Mexicali Valley offers
a plentiful agricultural workforce, Cox, 53, said in an
interview." - Bloomberg, Apr. 30, 2012.
