I don't know about in the US but for my engineering degree at an Australian university there were mandatory Ethics classes. One of the courses we were required to take talked about precisely this sort of thing the long term consequences of technology. I remember debating case studies in tutorial groups about things like Asbestos, CFC's, GM crops, cloning and the like. Being considerate of the unintended consequences of technology was very much something we were encouraged to think about. Another class we took covered the ethical responsibilities of an engineer, regulatory compliance, liability, disclosure, whistle-blowing and the like I still recall vividly hearing during a lecture the story of American Engineer William LeMessurier who was made aware of critical structural defect in a building he had designed and then risked his career and professional reputation to resolve the problem. I'm a bit saddened to hear other people have these negative opinions about engineering. A lot of us do take the moral and ethical implications of our work quite seriously.
