I noticed that I typed L. Randall Wray's name wrong in my post #6 above. I gave him a first initial of "W". It's not "W", it's "L", and the L stands for Larry. Wray wrote the book, "Understanding Modern Money" which, 18 years ago, aroused in me an intense interest in money economics. Wray, a Minsky protege, remains active as one of the key contributors to what has become known as Modern Money Theory. https://en.wikipedia.org/wiki/L._Randall_Wray
