The Mexican fruit was not allowed in until relatively recently -- except for certain times of year. That prohibition protected American growers.
We can thank the Chilean imports for breaking that set-up. Or curse them under one's breath sort'a like the Morro growers would.
The deal there is that the Morro fruit would come in late, and so pretty consistently would fetch a good price.
The changes made harvest strategizing difficult. I do not pretend to know the answers. (not enough information on when other harvests are most likely to come in, critical price points, etc.)
Your reference to Chilean ag goods reminds me that the money doesn’t all stay in Chile. A few years back, I was living there. A product for grapes and orchard use showed up, and. I was asked to give a bunch of talks at grower meetings. I noticed that certain names I recognized from earlier work in CA kept popping up. Long story shot, US growers from the Bakersfield area had bought 49% shares in many farms, brought in US technology, and were returning on capital 12 months a year. (Chile 6 month s out of phase, for those in Rio Linda)
