With respect to teaching, I couldn't make sense of mainstream economics when I had to teach it to college students. At the same time, I could see at the school that there was a whole lot of hypocrisy. Not much real respect for the "higher learning. "
The idea that all the people locked up in mental hospitals are sane while all the people walking about are mad is merely a literary cliche, put about by people who should be locked up. I assure you there is not much in it. Taken as a whole, the sane are out there the sick are in here. For example you are in here because you have delusions that sane people are put in mental hospitals.
