Cato Institute analyst Tad DeHaven, a former budget policy adviser to Sen. Tom Coburn, recently pointed out that state policymakers have become “dangerously reliant on federal money.” In a very real sense, state policymakers receive federal bailouts every year.

As the economist Herbert Stein famously observed: Something that can’t go on forever, won’t.

T.W. Shannon knows this. The next Speaker of the Oklahoma House of Representatives announced last month that he’s conducting an interim study this fall “to examine contingency plans for scenarios in which state agencies lose federal funding due to potential federal budget cuts.” Reminding us that “the federal government is now borrowing $1 of every $2 it spends” and that “our national deficit reached $16 trillion this year,” Rep. Shannon says “it is inevitable that states will experience drastic cuts at some future date. The spending level is not sustainable.”

According to the latest Comprehensive Annual Financial Report prepared by the Office of State Finance, Oklahoma’s total state spending is at an all-time high (see chart below). This money comes from a variety of sources. Nearly half of it is from the federal government; most of the rest comes from state taxes and fees that are either appropriated by lawmakers or directed to various agencies by state law. Total spending now exceeds $16 billion—that’s more than $500 per second—and it continues to increase every year.

And OCPA isn’t the only organization that has taken notice of Oklahoma’s fiscal profligacy. In a recent chart (see below), the venerable Tax Foundation reminded us that Oklahoma led the nation in government-spending growth over the past decade.

Oklahoma’s dangerous reliance on federal money is nothing new. In 2004, economist Barry Poulson wrote: “Oklahoma citizens may be surprised to learn that they have become an actual ‘welfare state,’ more dependent on the federal government to finance spending than their own tax-generated funds.”

Again, this is not sustainable. America is bankrupt. OCPA has recommended the formation of a legislative oversight committee designed specifically to review all state programs using federal funds. We commend Rep. Shannon for his farsighted and practical leadership in this area (and we suspect that anyone who has read Sen. Tom Coburn’s new book, The Debt Bomb, would join us).

Not everyone, however, appreciates Rep. Shannon’s foresight and fiscal prudence. The Journal Record, for example, went so far as to label it an “exercise in fear,” even using words like “quixotic” and “tinfoil hat.” And this is the institutional voice of a “business newspaper”! This is almost as surprising—and disappointing—as hearing the dean of a business school in Oklahoma, prefiguring President Obama, inform us that “the wealthy don’t become wealthy on their own.”

Rep. Shannon is correct. “We have to be ready to self-sustain core services and deal with potential cuts,” he says. “State agencies are addicted to federal spending. We need to tailor agency spending to ensure core government services remain unaffected.”

Core government services, by the way, are in the eye of the beholder. Oklahoma taxpayers should very much welcome a debate on what is and what is not a “core government service.” Core services or not, Mr. DeHaven has a suggestion for state policymakers: “If you want to spend more money than Washington will give you, go out and tell your taxpayers that you want to increase their taxes to pay for it.”

That’s not likely, of course. Both Rep. Shannon and Gov. Mary Fallin have said they favor lower taxes, not higher taxes. Fortunately, as Kansas showed us this year, tax cuts are possible. Kansas just enacted the largest tax cut in state history, and they’re not done yet. As the state’s budget director told me, “It’s amazing what you can accomplish if you’re willing to cut spending.”
