You may be totally qualified Blue. I'm sure you are. However, the post here deals with nepotism and it's clearly true in your case. Economy is using people like you to support his claim that "he's not the only one who does it". I think the other thing is that you originally stated you were only filling in temporarily and it has become full time. That being said, if you're doing the job, keep doing it and stand your ground. As I've always stated, most people would hire their relatives and friends if in a power position.
