State income taxes are ridiculously high in California. I did a comparison with neighboring state Arizona a few years ago, and the state spending per resident was about 40% more in California. The gap is probably more today. Schools, roads, state police force, and all the other state services are about the same in those two states. Salaries and wages are roughly 10 to 15% higher in CA, but the other 25% is all unnecessary bureaucracy and even higher spending on illegal immigrants than in AZ. And yet the people of CA actually voted for even higher taxes a few years ago. There are a lot of neurotic crazy people living in CA now.
