In which schools? The ” expensive schools”? I don’t know, but I have never met one from there, I have met am hoaratzim gemurim though.
From the ones that went to yeshivis that you say you get what you pay for, I have met many very serious dedicated talmedei chachomim. Many. And very knowledgable. I went to a shiur from one of them who did not speak English as his first language, yet when it came to medical related issues he knew and understood all the terms and the intact cues related to them. And based on what I read here way more and better than you.
As far as your claim about other “allegations” I have no reason to believe you or your source. I have seen a letter from the girl’s father in support of weberman.
