Neither Database Systems, Concurrent Programming nor Network Programming are foundational knowledge for CS. They are good knowledge to have for a specialized programming job, but not foundational computer science. It's like asking why someone with a degree in theoretical physics cannot fix my car. The real question is why so many people with CS degrees don't know what CS is really about.
