An interesting op-ed by David Brooks (no relation) in the New York Times on this subject can be found here.
It may be well worth reading for those in higher education that believe demonstration of "impact" and the like is the way forward. The critique is that the pot of money is likely to fall for all -- hitting departments with merit and less merit alike -- anyway. We work harder in the hope for similar or better income while likely receiving much less, if any at all.
Pessimistic? I'm afraid so although I'm keen to be convinced otherwise.
