Where did you get those numbers? I remember reading about one survey where the number of people with previous regime ‘nostalgia’ was around 50%. That survey had flawed methodology, and the results were probably mostly about nostalgia related to the times when we were young, and our backs did not hurt (obviously, Russian bots in my country keep blabbering about it ad nauseam as if it were actually about the quality of the old regime).

Let’s focus on the numbers that matter - the election numbers: in the 2025 elections in my country (Czechia), communists did not even get over the 5% necessary to get to the parliament. So, I guess what people actually remember here is communism not being better.
