I don't get it. If you have a great Ivy League program offering you an advanced position, in the field you want, I presume, why are you getting all bent out of shape over 2 "rude" PCs at other programs?
Oh, and by the way, as an attending, I would never assume my job is more important than anyone else's. Important, yes, but not more important. Some of the nurses at my hospital probably don't have as much education and training as I do, but if you ask me if I listen to their opinions when it comes to patient care, my answer will be you bet I do. They spend a lot of time with the patients, so they have pretty good insight. I will still do the diagnosis and treatment planning, but I will take their observations and opinions into consideration. I also notice you mentioned trash collectors as not being important. Has it ever occurred to you that without them, we would still be having epidemics of bubonic plague and typhus? Yeah. Those epidemics were caused by the infestation of rats and other vermin, who were attracted to, guess what, garbage. How about farmers? Many of them haven't even gone beyond high school, yet they still manage to feed the world's population. How about police and fire fighters? Again, a fancy education doesn't mean you contribute more to the world.
And as a resident, you should be very thankful for your PC's role. A PC is the glue that holds the residency program together. The PC is the one you will go to for assistance with credentialing and licensure, getting time off, getting LORs for fellowship, etc... And the PDs always listen to their PCs, because the PCs have been around for years and know what is going on with the program. And don't assume that their job is all that simple. It is a thankless task keeping things organized for a program with about 60 residents. And for what its worth, I had a PC who I thought was kind of abrasive at first. Guess what happened. She turned out to be like my second mom, and has done a lot for me, even after residency.
Seriously, I think a bit of humility on your part is in order.
