Any economic thought a bit further left than left-of-center gets quickly deemed "not economics."

Phrased differently, the field of economics dismisses any economic thought that doesn't serve the interests of capital and the people with the capital.

I don't think people take an issue with economists' predictions as much as their prescriptions. Younger econ doctoral candidates would do well to spend some time hanging out with the political scientists on campus. (They largely are doing this.)

The field will move forward one death at as time.
