Please don't besmirch Utah. It's one of the few high-trust societies left in this country. It's a beautiful, safe, peaceful haven and I literally never had a bad interaction there in years. And I'm not white.
However, my views on it of late are informed by seeing the local police being at the beck and call of a dodgy businessman and making up shit to try and scare off an investigative Youtuber: https://www.youtube.com/watch?v=cxZPfj8AlmY
The police were also so stupid, they accidentally released all their unredacted bodycam footage in their own press release, which revealed a pile of damning evidence against them: https://www.youtube.com/watch?v=Ih2XwNN0aVY
It's only one incident, but it doesn't scream "high-trust society". It makes me think of other corrupt small-town police forces with a bias towards residents over outsiders.
(Oh, and I also remember another Utah resident, the guy in the Cybertruck: https://www.youtube.com/watch?v=O0Dl0TnnK0E - he has deep-seated issues and that is such a goofy vehicle. He should sell it and spend the money on therapy)
But I think it's a good argument against GP's point. You may find the area you live is high-trust, kindly to neighbours, etc. But you can find stupid police and people everywhere, likely including your area. How can you be sure that visitors, neighbours, etc. agree with your experience?
It's probably axiomatic that a high trust society and a fully liberal one where everyone does whatever they feel like are incompatible. But we've got endless places for the latter and SLC is one of the few of the former.
