I’ve been reading up on the Great Depression (never say those of us at TPC don’t know how to have fun) and am struck by one overriding thought: Even with the benefit of 80 years of hindsight, economists still can’t agree on either what went wrong or how the economy got back on track. There is an important lesson here. Famously impatient, Americans not only expect government to fix today’s economic crisis, they demand it. Barack Obama, I suspect, will have about a year to turn things around before the public turns on him. Yet, if we still don’t know what happened in 1929, how can we expect policymakers to truly understand—and correctly address—events happening in real time today?
