Dr Chris Kirtley argues (12 Feb, 2010 p21) that a two year medical degree is sufficient: one year to learn about only relevant material and one year to learn about stuff that is not taught but necessary. However, that would devastate the universities, which are not benign organisations which most people assume it to be, but big businesses.

The longer the student stays at uni, the better it is for the uni since they get about $20,000 per year (from the government and from the student). Hence the mushrooming of postgrad med courses in the guise of more choices, when in fact they make no better doctors (Little benefit in postgrad med courses, AustDoc 22 Jan)
