I think that you're right that employers don't care about the specific courses that you took. I think you're wrong to assume that that doesn't mean that those who do take the more challenging courses do get ahead. The best networking I've done was in my challenging courses, where I met smart people who were also interested in learning and bettering themselves. My admittedly skewed and anecdotal evidence is that those people I knew who challenged themselves are now working at better jobs or going to better grad schools than those who decided to coast by.

I did not have a single situation where I did not know the difficulty of a course going in. While professors may not adequately let you know, any one of your friends or a number of websites make this information easy to obtain.

I feel like I might be alone in this, but I feel like if anything, a professor should warn you if they know that they do not challenge and push. You're in a university course -- it should be challenging. Courses should not be designed for an average student to excel.
