As Washington stumbles through yet another government shutdown, we’re hearing the usual chorus of panic: Headlines warn of catastrophe and politicians point fingers. The shutdown fight may grab media attention, but the real crisis is what’s happening when government is open for business. That’s the genuine “shutdown” Americans should worry about: A fiscal shutdown, when debt, interest costs and unsustainable entitlement promises combine to overwhelm the economy. Instead of obsessing over a government shutdown, Congress should focus on structural reforms to restrain runaway spending, especially on health care. If lawmakers can’t summon the courage to address the real debt crisis, the far worse shutdown — the day Washington can no longer finance its promises — will make today’s theatrics look like child’s play.
