University is overpriced, but a degree isn't just saying that you've gained knowledge. Being able to look up and memorize stuff doesn't mean you'll be good employee. if you can't work effectively with a team or tend not to finish a project all the knowledge in the world means nothing.
The most important thing most degrees demonstrate is that you can work for years on a project with multiple milestones involving multiple disciplines, work with others or self-direct, and meet goals.
