The G20 leaders recently called upon the leaders of the developed nations to employ more massive amounts of debt financed government spending to ward off the current economic stagnation and in some instances the early stages of recession. That fits Einstein’s definition of insanity: “doing the same thing over and over again but expecting a different result”. The pursuit of so-called “macroeconomic (fiscal and monetary) policies” has produced a quarter century of economic stagnation in Japan, a $30 trillion debt bubble in China with little to show, and stagnation and looming recession in Europe and increasingly in the US.
Einstein was a genius who remains relevant today. Just within the last few weeks evidence was reported of gravitational waves predicted by Einstein almost a century ago. Proving Einstein’s theories has been the focus of physics during the past century, but he maintained that had he been able to get an academic appointment instead of a position at the Swiss patent office he never would have been able to develop and publish his new path-breaking theories.
In his recently released biography The Courage to Act (2015), former Federal Reserve Chairman Ben Bernanke describes how, initially failing physics, he turned to macroeconomics as an outlet for his mathematical skills. This was auspicious. In physics, when your equations don’t fit the reality it is the equations that must be changed unless there is new evidence to change the understanding of reality. Einstein’s biggest error was rather than waiting for better data when his equations predicted an expanding universe, he fudged the equation (introducing the Max Planck constant) to fit the current understanding of a stagnant universe, then disagreed for most of his lifetime with the next generation of quantum physicists who proved he had gotten it right in the first place. Einstein’s one mistake is the modus operandi of modern macroeconomists.
