IMHO the high income tax regime found in California is actually a function of high density, high income, knowledge based earners moving in.
If enough of them arrive, demands for services (schools, fire, police) and infrastructure (i.e. light rail, etc.) will increase. The original NIMBY locals will initially love the increasing property values and new restaurants... until their property tax bills start rising to astronomical sums.
The state will then need to push for Prop 13 like property tax capping legislation at which point the state legislature will need to raise funds somehow and magically they will end up with a 10%-20% state income tax on super high income earners like Elon, et. al.
That said - just a IMHO prediction and just saying that you can't blame it entirely on just California(ns) being dysfunctional. :)
