Florida farmers plow under tomato crops

13. Why are 'prices plummeting' for produce, exactly?

And better yet, WHERE? They do not seem to be doing so at the Costco and Safeway I frequent

Or is this actually referring to prices paid to farmers for their commodities falling, and it's maybe because the rest of the world is refusing to buy from the US?

In either case I don't understand how the idea of 'less workers to pick the crops' translates into produce becoming less valuable? Seems like it would increase the value of the crops that are actually picked and ready for market. There must be something I'm missing
