Interesting that you quoted my response to Bio's unhinged rant, where I pointed out that literally every conclusion he leapt to was wrong. There have been several "critical thinkers" who have also concluded that I view a degree as purely transactional.
As I previously mentioned, I enjoyed classes from the liberal arts fields while I was getting my business degree, but there was no diversity of thought among the students who were majoring in liberal arts or among the faculty. Admittedly, this is anecdotal, but I don't believe there has been a mass movement towards rational inquiry in most universities in the two-plus decades since I graduated. I stand by my assertion that a lot of degrees are not of much value, in any way I would define it.
