No matter how high Schwarzenegger raises taxes, he's not going to fill the budget hole. It's the spending, stupid! And marginal increases in tax rates will be offset by decreases in taxable economic activity (investing, working, consuming).
California is doomed. For more on that subject, see here:
There’s good reason why most states won’t fall down the fiscal black hole where California now dwells. This is a state whose politicians, public sector unions and advocacy groups have been living in a fantasy world of overspending, investment-deadening taxation and job-killing regulation. Looking out over the state’s prospects and examining the budget deal that legislators have put together (jerry-rigged as it is with revenue gimmicks and unrealistic projections), the only question is who will be begging Washington for more money sooner, the banks, the auto companies or the Terminator?
The similarities between California and the auto companies are especially striking. Neither can afford their workforce. California schools pay their employees 35 percent more on average in wages and benefits than the national average (17 percent more when adjusted for the state’s higher standard of living), a significant bite because the state funds much of local education (to the tune of $42 billion last year). Benefits are a big part of these costs. A public employee in California with 30 years of service can already retire at 55 with more than half of his salary as pension, and public-safety workers can get 90 percent of their salary at age 50.
Another budget buster is California’s spending on social services, clocking in at about 70 percent more per capita than the national average. Leading the way is state spending on cash assistance programs (that is, welfare), where the state expends nearly three times more per resident than other states. There’s a good reason for this rich budget. California’s legislature has only reluctantly embraced federal welfare reform, and for years the state has had one of the worst records in moving people from welfare to work because state law limits the ability of welfare administrators to sanction those who refuse to participate in work programs.
