I'm not sure what to think of the University of Louisville being in the real estate business. Whether it's focusing too much on athletics, obsessing about intellectualism which is difficult to apply in the labor market, or doing stuff like this; I think "higher ed" often loses sight of its vocational mission.
Still, if medical schools find it pedagogically helpful to operate "teaching hospitals" to train medical students, residents, and fellowship students while keeping proffesors sharp - AND they can make a lot of money at it while providing a valuable service to many - then they should do so, and, maybe, business schools should operate a commercial consulting group and schools of education should run elementary charter schools.
