One can be critical of those subsidies but that headline is fairly polemic. The aim of those subsidies is among others to keep the agricultural sector in the EU alive. Losing the ability to feed the own population is a huge strategic risk. Is the system flawless? Absolutely not but it achieves that aim. Should foreign owned farms be excluded even though they deliver? That would certainly risk food production in parts. Or should all farms that are owned by nobility or former nobility be excluded? That would be even more consequential.

That said, subsidies are not only paid for quantity. There is also a focus on smaller farms or those benefitting society or nature.
