Ray Dalio predicts that central banks must carefully balance money printing to stimulate the economy and fight deflation, as too much will lead to hyperinflation and a worthless dollar, while too little will result in a major economic crisis.
"if the Federal Reserve Bank starts to print too much money well then you risk hyperinflation so this has to be done the money printing has to be done to stimulate the economy in a way that fights deflation without creating hyperinflation so it has to be done in Balance because if you do too much you create hyperinflation the dollar becomes worthless and now you create a much bigger issue but if you don't do enough well then you run a very big economic crisis"
