It also relies on people putting effort towards often intangible, uncapitalized, and unextractable shared value. So perhaps it makes sense that this is being diminished over time, as the grip of capitalism squeezes tighter and more efficiently. With more economic stress placed on individuals, people have less available time and resources to devote to things other than staying afloat.
Between polarization/politicization of literally everything and the relentless corporate desire to deconstruct society in the name of quarterly growth, I’m not optimistic this is making a comeback. If we want to teach the children anything, it is that The System has failed and is in dire need of replacement.
I think greed and corruption (cheating) by politicians and government employees has an outsized effect on this. Whenever you hear about it you lose trust and may even feel justified to cheat the system in turn. Basically they got there's, so I'll get mine.
IMO the penalties for corruption in public service jobs (all the way to the top!) should also be outsized to match the damage it does to society. I'm talking prison time. Also transparency at all levels and at all times. Public service should have really really good reasons to keep anything private and the default should be open to the public. There shouldn't be a need for FOI requests unless there's a good reason to keep something from being completely public.
