Even by the debt-laden standards of the day, California’s $16 billion deficit presents a monstrous challenge. It can only be solved by spreading the pain around.

This week, a nonprofit group called the California Budget Project issued a report detailing just how much Gov. Arnold Schwarzenegger’s proposed budget cuts would hurt schools and social programs. The report was sobering, as it underscored how vulnerable members of society depend on services provided by the government to continue to keep their heads above water.

But the report didn’t offer solutions, nor did it delve into the social costs of the state carrying billions of dollars of debt year after year. Those consequences, to taxpayers, future citizens, the state’s businesses and infrastructure and bond ratings, are also staggering.

To the chagrin of legislative Democrats, the fact is that spending cuts are an essential part of the budget solution.

So, to the chagrin of the governor and legislative Republicans, are some tax increases.

We can’t simply cut our way to a balanced budget, unless we are willing risk leaving the neediest citizens on the streets and public school students without viable and diverse sports, music and other programs. Realistically, we can’t tax our way to balance, either. Raising another $16 billion on the backs of taxpayers will hurt thousands of families and drive needed businesses, big and small, out of state or into threatening financial waters.

Meanwhile, voters have approved billions of dollars of bonds in recent years, the state’s prison crisis — which will prove to be very costly — remains unsolved, and voters hope to see expanded healthcare coverage with significant assistance from the government.

The California Budget Project report is an early shot as Democrats who control the state Legislature and the governor square off on the budget. Several months remain in the budget negotiations.

In our view, the real work of crafting a budget that will serve all Californians does not involve striking a noble “no taxes” pose, nor does it require spinning out disaster scenarios regarding people on the margins.

Sacramento has gone years now without directing the ship of state towards a safe financial harbor. It will be a test of this governor and this Legislature to see if they have the maturity to set partisan interests aside and stabilize the state’s finances before even more troubling times arrive
