I'm not clear how that would be different to the top-down economy and moral pretensions of bankers and investors that we have now.

When phrases like "moral hazard" are used to describe gambling risk, "amoral" is hardly the most apt description of a system that actually tries to define social and political morality for the entire world of work and business.

The reality is that mainstream economics has always been more a branch of moral philosophy than of empirical science. It's a tool of persuasion that tries to propagate its values through rhetoric and the use of economic, political and physical force.

That's quite close to the usual definition of a priesthood. It's only "amoral" in the sense that the ethics of the priesthood are quite alien to those of many adult humans.
