The true lesson to be drawn from business cycle history is that, if left to run their natural course, severe downturns are followed by rapid snapbacks. For example, during the 1921 recession, wholesale prices, industrial production, and manufacturing employment fell by 30% or more, reaching their low in mid-1921. But, absent government intervention, the economy recovered naturally, and by early 1922, it had fully recovered, from its mid-1921 low.

Far from saving the patient, government intervention (in the 1930s) came close to killing it. But you wouldn't know it from listening to the current discourse about the Panic of 2008-09. Indeed, politicians and pundits throughout the world have unfortunately dialed back to the Great Depression and drawn on the false lessons of history for policy guidance and justifications for their mega-interventions.
