Best thing that could help now is one initiative, or numerous initiatives, to roll back the spending initiatives passed by the voters the past couple decades. Start with Schwarzeneggers After-school Program passed by voters in 2002.
Worst thing that could happen is the state declaring bankruptcy. At that point either a precedent would be established with the federal government bailing out the state with borrowed money from China, or bankruptcy proceeding would take place with one judge deciding the fate of the state.
We need to repeal all the previously approved spending initiatives, get back on sound financial ground, put guns to the heads of the legislators with firm instructions to not mess with the renewed financial soundness, and let real prosperity return to the state.
Or, option 3, the state's executive branch would simply not be able to spend money that did not exist, without regard for the legislature's notions of "mandates" and "entitlements". If there's no money, the welfare checks don't come. Period.
