That’s incredibly tedious labor. I’m too old for it now, but even thirty years back, I would not have wanted to do that for more than one hour a day, if that. People never think about this part of food production.
The migrants also suffer here in California, because the Central Valley water has been largely stopped, diverted on brought to a trickle in order to preserve various and sundry field mice, lizards and ground nesting birds.
All suposedly endangered creatures, of course. What can I say, California majority elects these people who bring their warped ideas with them. These idea are usually trumpeted during their campaigns. You can’t say you have been tricked. They told you. We told you too.
Without the illegals, the work would pay more and be improved by automation.
