Which is to say I find the US is a high trust society where I live. I know there are other places where things are much worse.
It's been sad to watch it slowly get worse every year.
It goes for all things, not just petty/street crime though. Everything from business owners not prioritizing doing good work and building local reputation, employees slacking off as much as possible, investors demanding extreme profits at the expense of everyone else, corporations shipping out entire towns worth of industry to foreign countries, on down to actual crime itself.
It certainly wasn't all roses in the past - but it's a marked change from even my youth. Civic engagement is easy for anyone to see, and that would also be such a symptom.
One wonders how much of the high trust was a product of the immense prosperity unlocked by industrialization, some ameliorating reforms during the Progressive Era that mitigated the excesses of the Gilded Era, the New Deal, and postwar victory.
You'd think companies would value not killing their customers and market forces would take care of the problem, but, empirically, that's not how it has turned out. Customers are too far from the source; the incentives for fucking off are too high, and too frequently the food processors get away with it. Big-L Libertarianism is not compatible with safe food and medication.
They literally didn’t trust people to drink from the same water fountain
FWIW the only Anglo country left in the EU is Ireland.
So, it seems like their methodology doesn't actually match reality and is why I don't trust their results.
I might leave my laptop on a table while I use a public restroom in China, but I sure as hell trust a business partner far less than I would one in the US on average.
Cultures differ greatly in how trust is assigned and expectations. There are areas in Eastern Europe I would walk through a dark alley at 3am in the 'bad' part of town and not think twice about it. But I sure wouldn't trust their police force to not be corrupt and expect a bribe if they hassled me. The reverse holding true in a major city in the US.
What I observed was a deference to authority. Harsh government punishment for anti-social behavior is accepted and seen as the "role" of the government. While people in Anglo countries might protest against unfair government action, in Asian countries it's much more rare. People in Singapore grumble about how the government might punish behavior, but they keep those conversation to their family and close friends.
In terms of trust or concern, it doesn't extend much beyond the immediate family unit in Asia. I would say respect or concern for strangers is higher in Western countries Many people in Asia are happy to rip off others in Asia (if they think they can get away with it), but even the deadbeat cousin gets money from the family because "it's the right thing to do".
Very hard thing to measure.
In the USA and Europe I trust none of that. I've had cars broken into 5 times, bikes stolen 5 times, car stolen once. Reports of people stealing packages. I know I can't trust people at a coffee shop not to steal my laptop while I go to the restroom. Friend have had wallets stolen stopping to take a picture. etc.....
This means I trust no one in the USA or Europe. So to me, the USA an Europe are low trust societies.
