I have no idea where the "shunning" came in. The question was whether we should integrate undergraduate and medical education into a single program, ala the integrated BS/MD program. My point was that such a system would require that we judge who will be the best candidate based on their high school record. In my mind, that's silly.
But here, you're talking about changing the structure of undergraduate education, instead of medical education. If you want to shorten the time to a Bachelor's Degree, that would go against a century of tradition in liberal education, and would be an even more enormous feat than changing the entrance requirements to medical school.
A Bachelors in 5 semesters? 120 credits, that works out to 24 credits a semester, or 8 classes (6 with labs). Every semester.
That doesn't sound like any way I would have wanted to spend my undergraduate years.
