I doubt Keynes himself would approve of what central banks are doing today.  I think he would likely say something like "no no you missed my point and went too far".

Even Keynes knew he was offering a pyrmid scheme and knew full well he would be dead before it collapsed.   His famous statement "But this long run is a misleading guide to current affairs. In the long run we are all dead".   Well, in 1971 Nixon turned over the US monetary system to the ideas of Keynes.   Here we are approaching 50 years and the system is under major stress and yes, in the long run it will be dead only I don't think it will be that long.  Those who will be dealing with the aftermath in the not so distant future, won't have much good to say about Keynes.  That is those who didn't buy bitcoins instead of whole life insurance thinking it was an investment.

Today it costs the US mint 6 cents to make a 5 cent nickel,  will it cost 1 dollar 10 years from now?  AND a penny is 99 percent zinc with a bit of copper plating.  I still have 95 percent silver 10 cent coins which are now worth almost 2 dollars while a new dime is 10 cents which won't buy a loaf of bread but, the old ones are still good for a loaf of bread.
