Thankfully, we're not repeating all the mistakes of 1937. But Congress and the Obama administration are flirting dangerously with one of them by failing to extend the expiring low tax rates for all Americans. What's worse, we're close to repeating the mother of all policy errors, the one made not in 1937 but in 1930—the one that started the Great Depression. We're on track to resurrect the 1930 Smoot-Hawley Tariff Act.
Let's start with taxes. If today's low rates expire at year-end per current law, that would at a stroke reduce after-tax income for every working American, the average reduction being 3.3% according to the Tax Policy Center. Do the math: 94% of income goes to consumption, and consumption is 70% of gross domestic product. All else being equal, if the Bush tax cuts don't get extended, that's a 2.3% hit to 2011 GDP. That means instant double-dip recession, starting at midnight, Dec. 31.
