Farms are mostly located in sparsely populated rural areas. Because of the nature of farming, there are certain times of year when much labor is needed and other times when it is not. When it is needed (e.g. harvest) is when migrant workers come to the area, do what work is needed and then move on. There is not enough work to support full time employees and therefore people can not move to the area and sustain themselves. That's why Americans won't work the fields. They don't want to travel hundreds of miles for a temporary job and they can't permanantly relocate to an area where there isn't full time work.
