What's up with the OT and PT schools requiring a doctorate?

We area bit off topic, but before we go further devaluing our liberal arts tradition. I am going on the record saying that liberal arts tradition develops a more well rounded practitioner. (And remember that most Europeans are entering college with a thorough HS education, in general. They are entering college at the same level as an American with 1 or even 2 years of college under their belt) General Ed requirements such as humanities, english, philosophy, ethics courses and the like develop critical thinking and communication skills, all transferable to medical fields. We are in such a rush to cut out the superfluous and just focus on the nuts and blots. Sure the liberal arts stuff is not essential but ask yourself if it makes a better person?
