If you can't go to class for 4 hours a day or whatever, take notes, and do assignments, then how are you going to work for companies that require the degree and want to manage your time for 8 hours a day and give you tasks that might be just as menial? You chose your degree, you get to choose your classes, and for the core requirements, if the school is decent, you at least have the option of waiting to take it with a different teacher if they are that intolerable.
The ability to do tough work that you might not necessarily enjoy but must be done and do that consistently without stopping is exactly the reason companies require them. Of course they also want good talent that will contribute and make them more successful, but a large part of joining a company at first is training on menial tasks, working full time, and working well with others. It doesn't so much require that you have knowledge/skill, just the ability to learn the way the company does things, be absorbed into the culture, and be manageable. This also only gets you the smallest salary in the company, but it at least gets you your foot in the door so you can BE mentored and learn from others, just like you are supposed to be learning from your teachers/peers.
Many talented and driven people don't need that. They can find something that can make money and learn about how to accomplish that all on their own. However, although I am NOT one of those people, I assume that it is a rough road to take by depending solely on this talent. If you can tolerate getting a degree and showing that you can be obedient, you can make it a lot easier on yourself to gain more knowledge, talent, and resources by getting into a company easily. It's a big risk to depend only on yourself, because there is a lot of competition out there.
