Again, to the point that was just made, food is a very diverse system, so it depends, really, on the product and how integrated it is or isn't.
I think it's important to stress that profit in the food system is not a bad thing. Profit for farmers enables them to invest. Profit for truckers enables them to invest in potentially new and more energy-efficient equipment.
We need to understand that there need to be the right mechanisms in place to allow for everyone along the value chain to have a fair income to enable that, but also that there are the right forces in play to make sure it's not excessive.
