There are generally high trust and low trust cultures within organisations as well as in societies: https://www.whatsbestnext.com/2011/06/low-trust-cultures-vs-...

Both are effectively stable equilibria, so it's hard to upgrade trust across a society. And where it's possible to profit from breach of trust it becomes profitable for a few to turn a society from high-trust into low-trust, which I suspect is happening at the moment in the West.
