A high trust society is actually a good trait, not a bad one. It’s rather easy, lazy even, for a culture to devolve into a low trust minima. That’s basically the default state that people have endeavoured to evolve out of.
I think it’s also the kind of thing that can easily overwhelm anxious minds. The kind where “what if it’s a scam?” leads them to never taking a risk, donating to a cause, doing someone a favour.
Not that there isn’t a fight to be fought here. But waving the surrender flag on fostering a trusting society is a very weak move.
