The cure for both is pretty much: Live within your means, idiots.
All of the games with interest rates and monetary policy only work if you actually need to increase your money supply because of increased productivity/real GDP growth.
One of the reasons we have been able to get away with QE and massive borrowing for so long is that except for the period right before Y2K, Greenspan was restricting the money supply, effectively throttling our economy.
He was a fool: he actually once said that increased productivity causes inflation. Exactly the opposite is true.
Unless you have real GDP growth, the games played by the Central Banks are just a Three-Card Monte. When the shuffling stops and there's no there-there, who do you think is going to lose? It won't be Putin and his Oligarchs, and it won't be our 0.001%'ers.
