New Economic Perspectives has the article What if the Public Understood How Money Works? by William K Black. After he explains why the high priests of economics think it would be dangerous for the public to understand how money works, he mentions one way in which the information leaks out in times of war.
If you opened the box, you need to know that the MMT mentioned above is Modern Money Theory as Bernie Sanders’ chief economist is about to unleash upon the Senate budget committee. The other MMT that Black talks about is Monetary Myth Theory. This is what even revered economists such as Paul Samuelson wanted you to think you knew. He even has a Samuelson quote stating that Samuelson wanted the real MMT kept secret. By the way, the word modern in the Modern Money Theory refers to the era that started several thousands of years ago and continues to this day.
