That would be true in a free market but the EU’s Common Agricultural Policy actually incentivises over-production (it’s supposed to protect rural lifestyles). Dumping food abroad (i.e. at below market prices) then disincentivises domestic production there. It’s long overdue reform.

Looking at the 100’s of lines of comments, I presume they’re doing so too!

I think it’s useful to point to docs for unusual features but this is so verbose it makes it hard to see what the system is doing.
