California has structural obstacles that don’t fit into partisan politics. Proposition 13 limits property tax collection, which warps housing development and many other factors. Also, California has high incomes, which means Californians pay more federal income tax, and the state receives less back in federal benefits, to the tune of almost $100 billion a year. Those are significant headwinds that the state would still have to deal with even if it was governed well.
You really think california localities have a revenue problem? Prop 13 dos not limit property tax collection: it changes the distribution of it. It means I pay 40x more than my neighbor and that is very dumb, but whenver the city needs more revenue they just raise the rates.
Prop 13 is brought up a lot but it never made any sense to me that it also applies to commercial real estate used for businesses. I can see an argument for single family homes (primary dwellings) but property that large corporations own ? It makes no sense.
