This is not to say that firefighters are not essential workers, of course they are. We can make an argument that every firefighter should be paid 500k or 1 million. Heck, they save lives, so why not 10 million?
Ultimately, the vast majority of people not in public sector work doesn't get to make these kinds of arguments, and are simply forced to take market rates.
If it’s the latter then that’s an argument that compensation is too high if anything. It should be rebalanced such that some of it is used for training.
If the former then that’s just alien to me. Here in Australia firefighting is a prestigious job with a lot of competition. People volunteer to do it for free or do it part time while working another primary job, for years, in the hopes of being able to become a full time firey.
For any employer, private or public, slashing salaries and benefits is a great way to start trending towards 100% turnover, which is a pretty negative outcome if you want to maintain any semblance of operation.
Don't equate that with arguing for Austerity.

Are teachers overpaid, or are people in SF underpaid relative to the value of a house?
I don't know about you, but I'd have to compare it to cost of living references and public employee's per capita to begin to have an understanding. Even if I had that, there are many other factors I'd want to explore: what's the impact of CoL and commuting? What's the impact of employees not living in the jurisdictional area? What are the structural systems which function to determine salaries, both as an interaction with labor markets and those that have been institutionalized? If I was hired as a consultant to make judgements on SF public spending, in short, I'd do my due diligence.
