At my school, a lot of faculty members are racist or loser or drug addict or alcoholic or all the above. Virtually every non-white and/or non-jewish member of my dental school felt it is just a jail term so we pay our dues, serve our time, shut up, and hopefully get out on time. At some schools, grads who haven't passed the board get to volunteer to teach clinic; then later they'll advertise they were "faculty" of a dental school. There was a guy in my school who didn't pass the board until the 5th time. What did he do in between the period of repeatedly failing the boards? AGD, clinical instructor, and lecturing board reviews!!!
I can go on and on but you get the drift.
