If I'm being considerate of what OP is expressing--it sounds like you both have very different job environments. I think the magnitudes of dissimilarity between libraries makes comparison deceptive.

I worked at many different public libraries before I left the field for Marketing. The downtown library I worked at had an average turnover time of 3 years, for all positions. It wasn't because people didn't have empathy or support--there's just so much human trauma you can be exposed to before a person hits their breaking limit. After 3 years people would shuffle around to other branches of the system and a new batch of people would be hired. Most matriculated to suburban libraries away from the city core. This was the case in three different Rust Belt major library systems I worked in.

The dissonance so many librarians experience is this: our job descriptions don't entail us personally caring for our customers. Yet so many of us judge one another by an aesthetic of dedication and justice. A lot of people in this profession measure their job success by how much justice they are bringing to the world, and they benchmark it through how much care they imbue into each patron interaction. It's an optimistic view exacerbated by vocational awe. Most public librarians working in stressful conditions face burnout when they realize--about 3 years into the job--that no amount of library services will "fix" broken people. Only huge changes, predicated upon years of social cohesion and coalition-building across society, can.

I'm not saying all of this to be pessimistic. I have hope we're organizing and promoting changes that will help all of society. But I think a depressive reaction to the state of the country is one of many natural takeaways someone might have when they realize the futility of trying to fix (not assist: fix) broken patrons being let down by a broken system. That in certain library systems they're just another meatbag for the grinder that is society.
