In my case, I never seriously thought about several hot button social issues that were ethically troubled until I took a course on ethics. They simply didn't intersect with my life, nor did I expect them to. Only once I was in the class did I stop and think about costs incurred by choices and policies and their outcomes, much less how I might simply ask "What choice is more just (or less unjust)?"

College is about not only learning deliberately but allowing serendipity to open your mind to the unexpected. In my experience, budding engineers are among the last of us to become aware of social costs vs benefits and alternative perspectives. Without a required course to open their eyes, it's likely that many young techies will leap into life's choices before they look.

IMO, college is exactly the right time for all students to confront the cost of living an unexamined life.
