A big part of the problem is that pretty much all of the brutalist concrete building of the 70ies have problems if they aren’t straight on fire-traps they are mold infested places suffering from what the authorities often call sick building syndrome(https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2796751/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2796751/) combined with a massive urban housing crisis and a civic religion that forbids spending any significant money on infrastructure primarily used by the poor. It's a combination of decades worth of neglect to a set of buildings that were from day one at the edge of what we knew how to build and maintain due to a demand that they were kept cheap enough to be affordable on the declining working class wages. Fixing it is not going to be a few replaced panels here and there but a massive 10 year redevelopment plan to replace a lot of old 70ies crap with new buildings, in a political climate where nobody the political systems care about actually wants social housing to be a thing, and as always when there is a real problem the western way is to plug ears, close eyes and chant some feel good mantra.
