This...but a twisted, bloated, incompetent, and malevolently self-serving version of it.

Actual efficiency would dictate that there be only a relative handful of finance jobs, let alone very well-paid finance jobs. And that the vast majority of the money go to actually productive industries. And that the financial markets understand the principles and timescales of other industries, so they don't screw everything up with decisions equivalent to "Fiscal quarter ends in June, and Farmer Jones says he can harvest zero corn by then. Shut him down."
