I can understand this sentiment, but from my experience a lot of the value from doing a degree isn't from what you learn in class.

For me, the biggest value came from meeting other like minded people and being exposed to brand new concepts.

There's also value in learning how to finish things. I can understand that people drop out (for many reasons) and that's fine, but I think it's important to learn how to finish things off.

Although, knowing when to bail is probably also just as important. :)
