Or better yet, the parent should not be appointed to the position in the first place. If members of your immediate family occupy important positions in the industry you'd be involved with, then you don't get the job. Very easy solution, if the people in power were willing to do it.

This is kind of an absurd rule. The kids of the people who are seen as so good at their jobs to be appointed to public office are all the more likely to follow in their parents’ footsteps.
