I once met the guy who invented the phone menu system (press 1 for appointments, 2 for accounts, 3 for after market care, etc). He was a multi millionaire. As someone who used to work switchboard in the late 1980s, it was obvious where all this would end up.
We have created systems that are effectively barriers. And people are responding as if they're primed to fight at every turn.
Combined with this, there's now a scarcity of resources. No one was screaming about housing need in Birmingham in the 1980s because if you asked for a council flat as a single, childless person, then you'd get a council flat. If you went to hospital and needed treatment, then you'd be admitted on to a ward. In 1995, when my dad needed to go into a nursing home, his local government pension covered the whole cost. In other words, we're now putting people into impossible situations and then wondering why they're not saying please and thank you at every point.
I'm a teacher. The amount of anger directed towards me from parents is unreal. But it's not actually directed towards me. I'm just the person in front of them. They're angry because they're angry, often because they're poor and usually because they can't access services they need. I have to remind myself that anger is the other side of fear (remember it's fight or flight). It's a mess.
