Joseph:
There have been gedolim that possessed areas of expertise, without having attended college. The Skverer Rebbe had been involved so intensely and over so long a time that he gained considerable knowledge. I knew the rebbe, and while he was ready to impart advice, he was not beyond recommending these suggestions to the doctor. He never wrote prescriptions or performed surgeries. The Chazon Ish, having similarly gained hands on experience, was often able to access something we might call “Ruach Hakodesh”. And, while I do not personally know anyone who can do that today, I am not beyond believing that there could be someone holy enough today that we could say צדיק גוזר והקב”ה מקיים. Outside of their training, yes. But learned in this area, yes.
Our generation witnessed many rabbonim and gedolim completely outside their league with poor understanding of many mental health issues, including child abuse, domestic violence, mental illness, addictions, and others. Many proclamations made needed to be retracted, revised, and this multiple times. They are not infallible.
Lastly, there are many aspects to jobs, including location, tasks, training, work environment, wage, and more. I am trying to think of any Rov who is knowledgeable enough in all of these areas to be capable of giving advice. It is too easy to confuse approaching a Rov for his brocho with seeking his advice. I refer you to a wonderful article on that subject penned by Rabbi Yaakov Horowitz in one of the last issues of Jewish Observer.
A relative of mine moved a few years ago. Prior to making that decision, he approached several rabbonim, rebbes, etc., and asked advice. None knew a bit about the location where he was moving, not the community, schools, etc. They were unable to answer. He collected their brochos, but that was all.
