Anecdote : your comment striked me, as I was in almost the same situation (but with dead chicken, instead of dog) and my family member, very intelligent, highly respected engineer screamed at the child and hit the mother because "It was their fault". And this was one of the more "sane" reasons for their abuse.

Yes, that's why companies cut cost on security guards as much as they possibly can. From the product-making company standpoint security is a mostly a cost.

Also, private observation : Poland was relatively safe country during communist rule, although everyone was very poor. Then '90s happened, income disparity went through the roof, unemployment skyrocketed, and you could be greeted on the street by a group of young gentlemen asking you for your possessions, not to mention extreme gang violence and fights between hooligans.

European cities are dense, and there is limit to their growth, as they are often surrounded by tight circles of villages. Sure, you can build a few buildings there, but those villages are often fighting against high buildings, and residents often fight against urbanisation of the area. So you can't build suburbs like in USA and this makes the already problematic situation (high prices, big funds buying whole apartment complexes to rent them, many people buying apartments as assets and being afraid of renting due to protections towards tenants) even worse. So every building is worth it's weight in gold. And whole abandoned buying is going to be a daily reminder for many people that cannot afford to buy 1 room apartment about how unfair current situation is.

I don't want to argue about what to do with situation, just adding a perspective.

There is issue on the housing (apartment?) market, but it has nothing to do with communism, mostly with capitalism - big funds are buying apartments en masse (mostly new ones) and a lot of people started buying previously cheap apartments and renting them, causing prices to skyrocket in the last years.
