There is no such thing as a free lunch
I guess if mainstream economists use Milton Friedmanesque smears they think that will be sufficent to discredit Modern Monetary Theory (MMT). There have been a few critiques in the financial media recently along those lines. The authors tell their readers that they get the impression that MMT is just about a free lunch. Throw in Zimbabwe or Weimar are few times during the article and there you have it – rather tawdry attempts at maintaining mainstream thinking when the world has entered a new era of fiscal dominance as policy makers discard their reliance on monetary policy to stabilise economies. This policy shift is diametric to what mainstream macroeconomists have been advocating for decades as they repeatedly warned that high deficits and public debt levels and large-scale central bank bond purchases would lead to disaster. However, their predictions have been dramatically wrong and provide no meaningful guidance to available fiscal space nor the consequences of these policy extremes for interest rates and inflation. The world is leaving them behind and it is interesting to see how they are trying to reposition themselves.
