**Canada's Dairy Cartel** It's not a simple matter, and some US states wished they had the same price stabilization. Problem is that dairy supply has huge ups and downs, depending on the mood of the cows. Farmers buy a slot on how much milk they deliver. In order to meet the slot they plan for the minimum, meaning that at the maximum, they spill milk. The alternative is a free market where all the investment in a dairy farm can go to zero in a heartbeat.
