How is it a meme? The article literally lists instances of European elites chiding the lower classes for wanting AC, and spreading misinformation about portable units. It even recounts an instance of the AC being turned off during a heatwave on the floors of Ursula von der Leyen's building for regular staff, while the floors with chancellors and von der Leyen were prioritized and kept their AC. As the article notes: for all the talk about late-stage capitalism and elites, it's hard to imagine that happening in the US.
European elites as in a couple media figures and fellow extremely online people that professional internet opinion havers like him have convinced themselves control the world narrative. In reality AC is very common in Europe except in old buildings or poorer households, same as everywhere else.
This is the same level of analysis as Europeans on 4chan saying >be Amerifat >get shot, you're supposed to grow out of meme thinking upon becoming a mature adult
