The US/Scottish model has more than enough LA education embedded in it. That is what the first two years of college, and the Gen Ed credits, are for. Once you get into your junior year and above it makes sense to study/major/concentrate in one area so that is when you should be getting the specialized/preprofessional/vocational part of your academic training which can and should include an internship and capstone experience. So the two models are hardly mutually exclusive.
Regarding the so called downside of a preprofessional education preparing someone for a vocational field and then having those skills change and leaving the graduate out of luck almost all professional fields have some sort of continuing education to prevent that from happening. In fact, instead of looking at higher education as a 4 or 5 year period of someone’s life around the ages of 18 to 22 or 23 we would all be better off if we realized formal education needs to be related somehow to lifetime learning and continuing education credits. The human brain, I just heard, doesn’t even stop developing until 25, for example.
