First--- but you guessed it --
Arturo Rodriguez is a phony and the UFW is no longer a labor union, it is a front for left-wing lobbying (abortion, gays, illegal immigrants, name it: and name your price) plus personal income-enhancement for Cesar Chavez' children and grandchildren (Rodriguez is a son-in-law).
Second, UC Davis developed machines for picking every row crop and tree crop in California 40 years ago. The limiting factor is cost. But if/when wages go up, cost will no longer be a limiting factor. It'll all be mechanized. All of it.
