People think of robber barons twirling the mustaches when they picture the 1%, but for global topics, the 1% even includes people who are considered "poor" by western standards.
And, like the robber barons twirling mustaches people picture for their local 1%, you can't extrapolate any good data off of them.

People in the west are so wealthy that choosing to be vegan has become a status symbol, but when you hear "world gets richer", you need to be picturing people who can't afford a choice.
Both my parents grew up in villages where beef was like a few-times-a-year luxury, and of course as their villages have gotten more and more modernized, newer generations can't even imagine such a thing.
Now their country has KFCs...
However, many things that are now common where adapted by the broad populace because they wanted to copy/be as fancy as the 1%.
On of the most prominent examples is probably the British accent. ;)
You feel that way because you're disconnected from the poor being referenced by "living in central Berlin"
Living in central Berlin (Mitte), one of the most expensive parts of the city, it feels the opposite is happening.
Everything here is vegan or vegetarian at least.
Even a steak place next door to where I live has vegan plates.
On that note: it made me sad that all the dramatic changes you listed omitted the suffering of animals.
