I cannot be bought.
I can, however, be rented for a wide variety of legal and ethical activities.
Teaching stupid classes is neither illegal nor unethical. Not very productive, to be sure, but then I’m not the one that passed the law mandating agents attend the classes. I sneak in actual discussion of genuine ethical issues, including its history and philosophy, when I can.
It’s actually quite interesting when you can get a discussion going. Most people have never really had a serious discussion about ethics and where the line should be drawn in a specific case between ethical and unethical behavior.
