Beef returning to being a luxury item, as it was all over modern Europe until post-WW2 recovery. Non-wealthy Britons didn't eat beef very often, and it was also a special treat in Germany. Widespread regular beef consumption before the world wars was pretty much a big New World country (USA, Canada, Argentina, Brazil, Australia) thing.

Even today, Germans eat about 1/4 the amount of beef that Americans do, and somewhat less meat overall. It's certainly available, but it's a lot more expensive than pork or chicken. Domestic stall-raised beef is about the same price as free-range chicken, and free-range beef is even more expensive; I refuse to consider Brazilian beef, which is usually the cheapest, given its motivating role in the destruction of the rainforests.
