Earlier quoted context omitted.
Something went wrong in the US after 911. I don’t think it’s just the government. The entire capitalist machine realised just how profitable fear can be, and that’s been one of the big marketing angles in the 2000s. Especially in media, but elsewhere like supplements and drugs too. But the society wide impact of that has been a much more fearful people, obviously making parents more protective too.
The seeds were planted long before 9/11. I was born in the 80s, and even I saw something wasn't right. The Nancy Reagan War on Drugs and Stranger Danger were there already.
Also more subtle changes in how media reports things in general. I haven’t seen a study on this, but it would be an interesting subject.
