Republicans do have a revenue problem, veteran Bill Lockyer says

He found that a couple of big programs Democrats traditionally try to protect -- welfare and K-12 education -- actually have been costing the state less over the last decade after taking into account population growth and inflation.

Conversely, two major programs advocated by Republicans -- prisons and the car tax cut -- have grown significantly in cost.

Yes, the car tax cut is a very expensive state expenditure. That's because all the revenue from that tax -- the vehicle license fee -- had gone to local governments. When Gov. Arnold Schwarzenegger sharply whacked the fee his first day in office, he also -- in an act of budget mutilation -- generously agreed to make up for local government's revenue loss with money from the state.

Five years later, the fee cut amounts to a $6-billion annual state spending program.

"We're spending more on programs that Republicans don't want to cut," Lockyer says. "Yet, they don't want to raise taxes to pay for the programs."

Lockyer dug into state spending figures from July 1, 1998, to June 30, 2008, a period spanning three governors. They showed that when adjusted for inflation and population growth (a combined 4.6% annual rise):

* Welfare -- called CalWORKS -- declined an average 7.6% in annual cost.

* State spending for K-12 schools didn't quite keep up with inflation and population, falling slightly.

* The university system barely stayed even.

* Benefits for low-income aged, blind and disabled gained less than 1% annually.

* Medi-Cal healthcare costs for the poor rose an average 3.6% a year, far short of the runaway inflation in medical care.

* Prison costs increased 6.7% each year.

* And the car tax cut has cost the state about 25% more every year, on average.

Those big programs consume about 90% of the $103-billion general fund.

Lockyer's point was that although state government -- currently being battered by the slumping economy -- certainly has a spending problem, it also has an undeniable revenue shortage.

The treasurer unloaded his numbers on me after I called to ask how he'd solve the state's never-ending fiscal crisis, which flared again last week practically before the ink had dried on the new budget signed by Schwarzenegger. The state already was down $3 billion in projected revenue, and virtually everyone expects the hole to grow much deeper.
