Oddbean new post about login | logout let me ask you this then. where do you go to learn about these supposed "sound economic principles"? maybe at some point they were "two separate things" but they are de facto one now.
Well, you could learn on your own. The library is filled with good books on the subject. Or you could take economics courses in college. If you're actually interested, you could easily obtain a relevant syllabus from pretty much any university, and use that as a guide for your own self-directed learning.
