Is it the students? How many people are going into CS because they've had a taste of programming somewhere outside of school and decided they want to be a software engineer, and how many of them just get into CS because they heard that CS grads have very good employment prospects (Low unemployment, high salaries)? Anecdotally, I can tell you that during my senior project for my CS degree, someone in my group admitted to hating coding, but was pushed into CS by family, and that he couldn't code worth a damn.

Or is it the schools? In my school, the first two years were much heavier on the code, where the latter two years were heavier on CS theory. But in both cases, the quizzes and tests were on syntax and other things that could be answered with a short answer, or they were multiple choice. The only time your coding ability was tested was in the homework, which is easily plagiarized with Google and Stack Overflow.
