Annie Lowrey in Slate:
The overarching principle of the Do-Nothing Plan is this: Leave everything as is. Current law stands, and spending and revenue levels continue according to the Congressional Budget Office's baseline projections. Everyone walks away. Paul Ryan goes fishing. Sen. Harry Reid kicks back with a ginger ale. The rest of Congress gets back to bickering about mammograms. Miraculously, the budget just balances itself, in about a decade.
I know. Your eyebrows are running for your hairline; your jaw is headed to the floor. You've had the bejesus scared out of you by deficit hawks murmuring about bankruptcy and defaults and Chinese bondholders. But don't take it from me. Take it from the number crunchers at the CBO. Look at the first chart here, and check the “primary deficit” in 2019. The number is positive. The deficit does not exist. There's a technicality, granted: The primary deficit is the difference between spending and revenue. The total deficit, the number more commonly cited as “the deficit,” includes mandatory interest payments on the country's debt. Even so, the total fiscal gap is a whisper, not a shout—about 3 percent of GDP, which is what economists say is healthy for an advanced economy.
So how does doing nothing actually return the budget to health? The answer is that doing nothing allows all kinds of fiscal changes that politicians generally abhor to take effect automatically. First, doing nothing means the Bush tax cuts would expire, as scheduled, at the end of next year.
