Nova,
I do not agree with your assesment, the differences IMHO are not moot. People are different and one style or frame of mind may not fit someone else. Case in point, I have a very good friend that has the same IQ as me and I consider to be every bit my equal. In college this friend carried a 3.7 gpa. I on the other hand struggled to pass any class. Later I entered a self paced program at the same time as my friend. I came through it at the top of my class while my friend struggled the entire time. We both have our strengths and weaknesses. The two different styles of learning only showed the difference in how we accumulate knowledge. There are differences in all of the agencies, some are big and some are not but there are still differences and one may be a better fit then the other for a particular person, their background, and their experience level.
