I think some of it is just good ole western chauvinism liberal arrogance

Another part of it is that most westerners alive today have spent their whole lives saying and being told that all that bad stuff happened in the past and that everyone’s more civilised now. Slavery, colonialism, genocide, these aren’t core aspects of capitalism, they’re things that people used to do before ‘everyone’ suddenly realised that they’re wrong.

So when looking for ‘an institution that they trust’, the list is very short because (a) believing the institution means revaluating everything and (b) they’ve also been told not to trust many institutions or any institution that requires point (a) to happen. It’s easier to take names off the list than add them.
