The "hey, I've got a family to feed" argument is pretty weak. A lot of people have families to feed. A doctor is not going to behave unethically just because some "business exec or MBA" told him to experiment on babies. They take their oath seriously. We ought to have a "do no harm" oath also, and we should take it seriously, too. At the very least, we should apply the "Would we want our name and face all over national newspapers associated with this code?" test.
