California has a referendum system. That so few referendums focus on cutting costs says something about its voters’ priorities.
On the other hand, the state is losing population on an absolute basis (and relatively even more so against a backdrop of national growth). So some folks are voting with their feet. I'm eagerly awaiting the day when I'm free enough to do the same.
I’m arguing the opposite. The voters have the tools to oppose the state government’s size. That they don’t use them signals support in broad terms.
One key difference that I do like about the CA referendum process is that laws passed by referendum in California are equal to the state constitution and require 2/3 supermajority in state congress to modify or change, just like the state constitution itself. This avoids many attempts by legislature to foil or spoil the will of the voters’ referendums, in contrast to other state referendum processes which are only considered a law passed by other means and are usually able to be modified by simple majority.
