My experience has been the exact opposite. For example, the only competent Java developers at my company have been myself (no degree in anything) and a guy with a degree in physics. We've spent the last two years cleaning up the mess created by the completely incompetent jackasses who came before us, one with a Masters and the other with a Bachelors in CS. The situation was similar at the last company I worked for.
The open source community has much higher standards than the academic and commercial communities. In the OSS world, nobody will take you seriously if you publish a Java library without Javadoc. But in the commercial world, highly educated shitheads still think MS Word is an appropriate format for API documentation.
