Neo classical economics is actually a regression even vs classical economics. The moment it became a hard science it lost the human element and became someone's optimization fetish even though nobody can even know what it optimizes for.

The even worse part is that some assumptions don't even work in once you look at the math of e.g. accounting.

Keynes and Silvio Gesell and Wolfgang Stützel are much closer to how our accounting system known as money works even though both of them lived during a gold standard where it was normal to bend some accounting rules like digging out new gold to create more money or just bend them outright by printing money without any asset backing it.
