White collar vocational training is sort of a new concept. Like last 50-90 years concept. Engineering became human engineering became business school. This is the university level vocational training alluded to.
I think the thought behind that may be a well rounded education will help you to make better decisions (ethical and moral decisions). You've heard that people study history to avoid repeating it. After a liberal education, then you work for a company where you learn how to do your job.
Really this is so different from the way things are done that it is hard to conceptualize, but was the way of the world for much of the world's history. You became an asset instead of an unskilled (or just as skilled as anyone else) minion. You also have a little perspective, not just an ability.
Of course there are lots of situations that this makes no sense. I want my doctor to know his vocation before he starts cutting or putting fingers in dark places. If, for example, you make me something that I need to depend on, I want every minute of your BSME behind it.
However, I wouldn't mind if someone handing out loans had spent a few years thinking and arguing about what is right and wrong. Give that CEO The Republic and get him to think about it. There is a lot of power in some jobs and sometimes it seems like we just gave monkeys bigger guns.
It is situational, but the thought behind education (think public education) is that it makes better citizens. It helps people know that they need to use their brains before voting/buying/whatevering and not just do what the tv box says, or what they can get away with.
