When the hell will there ever be mechanized crop harvesting to end the cry from Rinos, Chamber, and the Left that we need mass immigration of Mexico slave labor?
If already exists for some crops, and has for quite some time. But farmers could get the job done cheaper with illegals. So our lettuce was cheaper, but taxes higher to pay illegals welfare. When that cheap labor is not available, the farmers will get the mechanical harvesters or find legal workers at a price they are willing to work for.
A big problem is that farmers need seasonal, short-term labor and with a robot you can park it for 10 months and it will not complain. Also, imagine a service using uber technology to share/allocate automated agricultural robots during the harvest seasons; robots could work 6 months during the US summer and then off to Argentina/Chili for their summer. Even within the US micro-climates and latitude would mean that agracultural robots would start harvesting in the south and work their way north.
Besides, I am sure that if an agricultural robot was idled for whatever reason an entrepenuering farmer could always slap a wig on it and there would be quite a few maladapted manga-reading perverts that would pay money to molest it.
