Farmers still complain over falling milk prices, and that they cannot survive. Yet the market is still saturated, milk was literally drained down the gutter regularly, every milk product is incredibly cheap IMO, considering how it is produced (although there was a butter shortage and a price "spike" last year).
Subsidies (and even worse EU wide subsidies) seem to do more damage than good in the long run.
It’s important to understand why they are there. There are not there because states are scared of food instability. Austria for instance tracks how much of the daily food intake it can produce locally and there are yearly goals to make it 100% self sustainable.
If that goal is still important as EU member I can’t answer but it’s still a goal.
When staying particularly in Austria, the subsidies are there because national politicians and EU politicians from Austria want some part of the EU subsidies pot for their farmers, contributing to the general constant rope-pulling and trading "a piece of the cake" (i.e. EU budgets) - usually in the form of: "You get subsidies for x, we then get support for our poor farmers in poorer regions, since they are starving".
Generally the EU subsidies for agriculture are misguided and just money down the drain. Until they begin to dry up causing uproar and "EU took our money!"-complaints.
