... is, afaik, based on the absence of subject diversity in a "school." Thus, the Engineering School or the Nursing School affords the student such a concentration, while a true collegiate education covers a breadth of subject areas. My undergraduate degree is in Mathematics, which is (along with the sciences like Chemistry and Physics) a degree concentration in the College of Liberal Arts. There is no question that the Mathematics training offered a mental discipline that was invaluable, I find that the richness of my life was enhanced immeasurably by the diversity of coursework I did outside of Mathematics.

When we think of 'college' as a vocational school, we lose. All of life, both vocational and personal, is enriched by the synergy of our associations with others ... others with differing educational backgrounds. When we have some basic background in a diversity of subjects, we're better able to enrich those associations.

There's a reason it's called the "Business School" ... since they graduate the narrowest and least attuned people on the planet. (IMHO.)
