Most of it was not being utilized, and still isn't. because it was very expensive, and labor was too cheap for the machinery to be cost-effective.

Bring on the machines. Seriously, it's time for a farm machinery revolution.
I clearly recall reading an article, late 80’s, in the San Jose Mercury News.
It stated that funding for final development of tomato harvesting machinery was being pulled due to pressure from the Chavez/Union folk.

That’s over twenty years ago, modern computer capability should have helped to advance the speed and capabilities of such equipment.
Cost should now be lower too, time for “Made in China” to finally yield some actual benefit!
