California passed the budget a month or two ago, and the vouchers ended then.
One root cause of the problem is the fact that it only takes a simple majority to pass constitutional amendments by initiative. One such measure requires a 2/3 majority in the legislature to pass any budget. The result is the partisan gridlock we've been seeing for the past decade. There is a proposal to alter this amendment by requiring a 2/3 majority only for new taxes, but allowing a simple majority (or a 3/5 majority) in the legislature for the overall budget.
Another root cause is the loophole in property tax caps for commercial properties. The assessments are limited during uninterrupted ownership, but commercial property owners get around that by creating dummy holding companies, which allows them effectively to buy and sell commercial properties without triggering the re-assessment.
As a result the state budget is heavily dependent upon income and sales taxes, and with the recession that source of income has been dramatically reduced. We also have a huge prison population (can you say, decriminalize light drug use/possession?) which is quite costly to maintain. The prison guard union has become quite powerful and blocks most attempts to cut costs. Then there are the entitlements, required by law and not something that can simply be sliced out of the budget. Public employees are often overpaid in relation to their counterparts in the private sector, and the fat pensions awarded to police/firefighters etc. only consume more and more as these folks retire at a relatively early age (50's) and get at least 90% of their salaries plus extra medical coverage for the rest of their lives.
Our local school superintendent gets over $350,000 a year in salary - in a town of only about 70,000. What's up with that?
