Old Professors, Unlike Old Soldiers, Don't Fade Away
Paul L. Caron at TaxProf Blog on the issues of tenure and old professors who won't retire.
The question of tenure generates surprising reactions. I know of one conservative commentator who believes that abolishing tenure would result in the firing of conservative professors in predominently left-wing departments.
My idealistic take: No mandatory retirement. No tenure. Strive for intellectual diversity. Get rid of incompetent professors regardless of their age.
