Most governments and municipalities do a horrible job of articulating what their constituents taxes go towards. People see giant buckets and have a very hard time converting that into what they see and use day to day.
Of course make government more effective and efficient. Very few would argue against that. But at some point, there’s just nothing to trim. However if one’s underlying assumption is all public spending is bad, then of course there’s more to cut, it’s just that the argument to justify the cut is disingenuous.
Granted under funded pensions are often an issue, but that's a effectively loan the local governments have taken out. Their problem is debt not the upfront costs involved.
PS: I tend to put all taxes into the same pool as I care less about the specifics than how much I get to keep after Social Security, Medicare, Federal, State, and freaking Local all take their cut.
