Yes they do? Farmers are share holders and Frontera need to make a profit to pay back to farmers. If the industry tanks so do they?
Interestingly, the area where I live was once heavily invested in forestry, mostly native harvesting. The govt. put a stop to that, rightly due to disappearing native forestry. The town nose dived and the population halved. It's a shell of what it once was.
Forestry is beginning to reappear, so the town is unlikely to disappear as many try to report. It will just change. Hopefully some of the dairy will convert to crops (oats) which will see a future, possibly better than now.
My reading of the history of the area where I am, indicates that dairy has NOT contributed much to the prosperity of the area, but there are some wealthy dairy farmers who will sell up with plenty to retire on. And move away taking a lot with them.
