An interesting and informative post. I expect that the same has happened here, while Hutterite collective farms seem to be doing well. Some areas of agriculture in Canada control production by Boards.
Dairy farmers have quotas.
These boards are under attack as part of trade liberalization as is the Wheat Board marketing monopoly. As in the number of farms have been declining and average size increasing. However, size does not necessarily bring profitability. Some very large farms are in serious cash flow trouble and some go under. Smaller family farms may survive because family members work off-farm as well.
