I also do not have a degree, though I'm at year 13, and I've learned those lessons you said earning your degree taught you. It is good that you learned those lessons, but your conclusion is specious bordering on elitist.
I do have a large gap in knowledge. I made a great leap over a mountain of theory and low-level practice that I must fill in, but I (lucky for me) didn't need college to teach me humility and how to be receptive to learning (even when I "know" I'm right). The more I fill in that gap, the more I realize exactly how big that gap is, and strangely, the gap grows as it fills.
The point being: Though a university degree is how you reached... well... enlightenment, there are many paths. And if you meet the Buddha on the road, kill him.
