I'll bet many, if not all, of these farmers are locked into commodity production and do not sell their product(s) directly to consumers. I'll further bet these farmers haven't heard of producer/consumer co-ops either.
Until farmers capture the consumer dollar they will remain ill-payed for their work while watching the middlemen and grocery/food stores reap the majority of the profits.
EU regulations on pasteurisation, sterility, and the equipment required - often ludicrously prescriptive - also makes it almost impossible for individual farmers to raise the capital required for even small scale craft production. The increasing dominance of the retail market by global supermarket chains also cuts off direct access to the vast majority of consumers. Farmer's markets exist but they operate on the margins.
There are many regulatory, technological, capital, and economic barriers to direct market entry and it is very difficult for many farmers to survive without being caught in the corporately dominated supply chain. notes from no w here
