That's an interesting question. I was listening to a previous meeting, and I think the same question was asked: whether supply-managed commodities seem to have less stress than open-market commodities. When I was farming, I had hogs and my neighbours all had supply management. I don't know if we were less stressed or not. I know that, because I was a hog farmer, I had to deal with much more volatility in my pricing. But there were also some pretty good years that my supply management neighbours didn't have.
As a general rule, I would say that, if you're a top performer, supply management offers a bit of income stability that the other, more open markets wouldn't have. One of the stressors is always price volatility, so I would assume that it would have less stress. Part of the challenge is that if you're looking to grow the farm, it is much more difficult within a supply-managed industry than in another industry where, if you have the capital and the business plan, you just make it happen.
I can't really answer your question as well as I would like to.
