And why should I simply assume that "Education Economists"* really know the subject they purport to talk about? Because they are credentialed members of university departments with some label? Because a few of them won some Bank of Sweden award?

Just because a particular department or field of study exists in academia does not magically give them the imprimatur you think it does.

* Btw, I know for a fact that a few of them are not "education economists"
