Essentially, MMT is a misguided attempt to deal with insufficient government income / funds.

Typically, governments make money by collecting taxes or by selling bonds. MMT holds that needy governments do not have to collect more taxes or sell more bonds. There is a third way, and that's MMT.

MMT may be cloaked and disguised as a clever new policy, but for all intents and purposes, it's basically money-printing.

Certain overly clever central bankers such as Greenspan and Bernanke explicitly condoned MMT. In certain ways, they even resorted to it. They essentially said that they US had access to an unlimited supply of money, cuz it could simply print more and more.

But any fiat money, printed out of thin air onto valueless bits of paper or clicked into being by using a computer mouse, will eventually revert to its actual value – which is zero.

On the way, the money produced according to MMT will create bubbles and eventually hyperinflation. As well as lots of pain and misery for those who are impoverished by it.

Anybody who thinks that MMT is a viable alternative has her/his head stuck in the sand ... or else somewhere else dark and smelly. MMT is Magic Money Thoughtlessness.
