Unease about economic policies

One cannot help but feel uneasy when looking at economic policies in OECD countries, even though the goal of the highly expansionary monetary policies is understandable , The considerable growth in public debt, even though part of this debt is held by central banks, is incompatible with a significant rise in interest rates. But yet, there are many arguments for expecting inflation to rise again in the medium and long term; The surge in the quantity of money will most probably lead to a sharp rise in asset prices (equities, real estate, etc.). Does this mean that we accept bubbles and the increase in wealth inequality? For proponents of Modern Monetary Theory, fiscal policy can be as expansionary as necessary or desired, and money creation prevents interest rates from rising, while inflation is prevented by discontinuing the policy once full employment has been reached. However, they overlook: The possible return of inflation for structural (ageing, energy transition, relocation) and non-cyclical causes; The risk of asset price bubbles.
