There are still plenty of poor people who can't afford meat in every meal, even in rich countries. And even with mass meat consumption there is still further delineation like grades of meat that is plenty for rich consumers to differentiate themselves from (most people certainly cannot afford to cook Kobe/Wagyu with every meal)
Yeah, obviously as you say there are reasons to suspect that effect isn't fully applicable (yet?) and to whatever degree it is it hasn't dominated overall. It just seemed relevant enough to share.
