I'm not convinced it is under funding. It could also be too many managers and not enough front line staff. Or it could be too many regulations making the process need far more time (time=money).
I watched pretty closely while I was changing from a KY vehicle registration to a CA registration. The staffer was plenty quick, there was just an absolute heap of stuff to do that all seemed pointless. I'm sure each of those little legally-mandated whatsits was well-intentioned, but in aggregate they bedraggle getting anything done. Similar story in zoning / planning. And in both arenas the result is that doing things is slow and expensive. Please, government, spend some tiny modicum of effort on deregulating and streamlining for the sake of not wasting my limited lifespan.
I don't know, but I lean to too much process.
