I wound up on a plane with a professional business shrink who worked in Austria, where many companies are family-owned & particularly nasty things happened. She said actually most situations were quite amenable to treatment and the bullies often lacked self awareness and changed when they learned perspective, and their co-workers learned to change the context. I'm sure that's not true in all cases, but it may be that most cases would improve if we just increased the percentage of people educated to the problem and its solutions (including training for the executives.)
