The way I remember it is that the EU tries to keep crop prices at levels that would reward farmers with a good living yet not cause riots by consumers. So at least they are aware that consumer riots are always a possibility and not something positive for their control of agriculture.
I think that the Left is always probing (probably unconsciously) to see how much it can get away with before the peasants riot. It's probably passed time for action on the part of the peasants.
Why am I not surprised?
