Agreed. I only mention engineering students as my only experience with ethics classes are in that domain. However it's still a good example for engineers, particularly how the design failures resulted in deaths, the role of whistleblowers and how disastrous self-certification can be.
I would be utterly shocked if any MBA program in the world had a mandatory ethics component, for all that an unethical MBA is in a position to kill many more people than an unethical engineer.
