If you think of it as wasting time, then your attitude will come out in your work. All those classes you don't care about are there because university isn't trade school.

The more interesting work goes to programmers who can communicate. 90% of programmers can get the job done; I want someone who can articulate what he's built, how it can be improved, when it will be ready, what needs to be changed, what we're doing wrong, etc.

That's what all those classes you don't care about are for: giving you perspective outside heads-down coding that can be outsourced for $50/day.

You'd be amazed at how many people I have interviewed that simply either can't, or won't talk (from the interviewer's perspective they are the same thing!).

Again: most halfway decent programmers are adequate. The great ones are great not because they can write code, but because they can explain how that code works to someone else and, vice versa, they can understand someone who is trying to explain why the code doesn't do what they need. That is worth paying for.
