Take the agricultural policies in the EU. They want to correct against overproduction while doing ecologically good but they interpolate of cause from past data. Now take the hottest year on earth to come in 2027 due to El Nino and that collapsing already strained expected harvest and you are looking at reasonable policies producing starvation, due to a inability to plan for a future not in the data yet.

And the whole glut is artifical in the first place because surplus wheat is not allowed to be used as energy, no it must rot in storage snd get "animal grade" before you can use it otherwise. The whole reason the eu system still works is because the traders largely ignore the central planing system, shipping things from high regulated eu countries to "i dont give a f**" countries, recertify it there and then reimport.
