Its a layer separation problem.
You are noticing participants within a localized system responding to issues from within that same system. It's similar to asking people to judge themselves correctly. Many people fail to accurately map their own shortcomings because they are doing it from within the constraints of the same system.
To an outside observer the logic may not make sense. What can sometimes seem obvious from outside doesnt necessarily transfer to participants within the system.
You are taking explanations to why the system is behaving the way it ...
Institutions diffuse responsibility through hierarchical structuring. No one participant/employee is fully accountable for systemic failures.
You're examples were employees responding to their own layer of accountability within that hierarchy.
