You are correct in many ways.
The yeshivos have to “dumb down” the curriculum because not everybody in the class/shiur can keep up with a fast paced learning speed. So the really smart guys or girls for that matter arent challenged and they dont get to fulfill their potential.
Additionally, we accepted too low of a standard as ok. Its just ridiculous.
I really think things need to go back to the old way where there were special yeshivos for the Metzuyanim. There can be Yeshivos for Metzuyanim and yeshivos for regular people but the smarter kids deserve a harder more challenging curriculum geared towards their potential. But that wont happen because every rich guy will pay to have his mediocre kid in the yeshivah, and unlike in prewar Europe the Rosh Hayeshivos of today dont have the backbone to say no you cant buy your way in here.
