Obviously a lot of effort went into this film and it does a good job of conveying the area farmers' and workers' viewpoints. It's never been a secret that farm work is hard, never-ending, time-critical work -- I don't disagree that it's well-suited to Mexican laborers who are young, strong, dependable and hungry for jobs. A solution to keep dairy prices low indeed might be, as the piece suggests, to provide an avenue for dairy farmers to use guest workers who would otherwise not be eligible for employment or residency in the US. It would be nice to see income taxes paid out of these positions.
The question of whether to allow that is a political one. Currently the law states that these jobs ought be kept for Americans. I think an alternative solution may be to get very tough on farmers caught using under-the-table labor. Think criminal court or serious fines. If farmers were kept from under-the-table hiring, farms would have to compete on wage with each other and with other job sectors in order to attract eligible workers.
While I don't begrudge public assistance to those people who need it, I suspect more could be done to match healthy people to available jobs. Yes it might mean moving out of the city to the country. It's always been a good place to have a family and raise children.
