In the U.S. they put up fences and shoot people who go inside.
I understand exactly how you feel. If you are as competent as you sound, find a new job and then leave. Make sure the new place is more stable, so you can keep your conscience clear. BTW, +1 for having one.
I cannot draw a cart, nor eat dried oats; If it be man's work I will do it.
