The kind of culture that comes with being a place where young, highly educated, liberal, high earning people come to work and live. It seems like that final bit is the problem for these campaigners, they seem pretty enamoured with the idea of their city staying poor (but sexy).
It's not poor. It's just sort of cheap, quite affordable compared to other places.
But if locals want to keep it that way, then they need to show that they are the majority in that municipal area, or they should have bought the buildings a long time ago.
Or at least strategically important flats (the cheap ones on the ground floor next to the hallway, or just simply the cheapest ones, maybe just a lot in the basement, that grants private property rights) - though it depends on the co-owned property rights in Berlin/Germany, but I hope a condo cannot be sold without all the owners agreeing.
