Back in 2003, I was perusing some state budget documents and found an interesting correlation. When state general-fund spending rose above 6.2 percent of the income of Californians, inevitably the state would run deficits, get into budget trouble, and end up having to make sharp budget cuts and tax increases.
I noted how it was like carrying a burden on your back. If it’s 10 pounds, then for a healthy person it’s no problem. But 20 pounds for many people is pushing it. Put on 50 pounds and you’re slowed down sharply, and many people might not be able to walk more than a few feet before resting, even falling.
A spending burden of 6.2 percent or below is tolerable in California. Above it causes problems.
In early 2005, Tom Campbell, then the budget director for Gov. Schwarzenegger … visited us for an editorial board meeting. I showed him the graph.
Even With Revenue Declines, Spending Remains Above Historically Recent Peaks. Since around 2020, the state has seen historic surges in revenues—and ensuing historically large surpluses and spending levels. However, while revenues are moderating from the recent peak, they are still above average historical levels. For example, even after adjusting for inflation, anticipated revenues for 202324 remain about 20 percent higher than before the pandemic. Moreover, the Governor’s proposed spending level—as a share of the economy shown in Figure 3—remains above peaks from the early and mid2000s. None of these levels—both on the revenue and spending side—are consistent with shortfalls seen during recessions.They didn’t mention the 6.2 percent limit—Seiler’s Law. But you can see it anyway if you mentally draw a line across the data points at 6.2 percent, as I did in my graph. They also didn’t mention my discovery. Perhaps they didn’t know about it and figured it out on their own, much as Newton and Leibnitz discovered calculus independently.
Let me here update what happened after 2010. What happened was the voters put Gov. Jerry Brown back in office. One thing he always was good on, beginning with his first stint in the governor’s chair in the 1970s, was keeping budgets under control. Elected again in 2010, during his eight years in office he made sure the spending/personal income ratio never rose above 5.8 percent.
- 2019–20 5.56
- 2020–21 5.87
- 2021–22 7.39
- 2022–23 7.96
- 2023–24 7.10
As the Great Recession hit in 2007 and Schwarzenegger’s box-expanding spending increases couldn’t be sustained, revenues dropped $20 billion in one year, causing $40 billion deficits. Could it happen again? We’ll soon find out.
With the LAO now warning about the 6.2 percent limit, perhaps governors and legislators will be more prudent. Well, maybe.
