I've also pointed to growing support for that contention in major media outlets. The most recent occurred today in a BBC editorial denigrating no less than Harvard Business School.
It is ironic that the more prestigious a college, the worse the instruction is likely to be. That's because colleges gain most of their prestige from their professors' research productivity, which is inversely correlated with the ability and desire to teach. Also, compared with low-prestige colleges, prestigious universities spend a higher proportion of their budgets on research.
Designer-label colleges can get away with charging so much and providing so little because students are brand-name driven in choosing a college, knowing that, with a designer-label diploma, employers will hire them, whether or not they learned anything at college.
Interestingly, the BBC invited Harvard Business School to respond to the scathing segment--Harvard declined to.
