Nice discussion HERE including a cool shout out to friend-of-the-blog L.A. Paul. Most horrifying part:
What percentage of graduate students end up with tenure? (About one in four.) How much more unhappy are graduate students than other people? (About fifty-four per cent of graduate studentsreport feeling so depressed they have “a hard time functioning,” as opposed to ten per cent of the general population.)
Ouch. Ouch. Ouch.
