Your post is long in complaints, but short in solutions. If you truly want to convince people to move in a different direction, provide some suggestions or ideas.
Here is one small step. Yeshiva high schools can take more seriously basic mathematics and writing.
The idea of a Yeshiva (Al Pi Rav Dessler, and what many of the “Frum” Yeshivos hold L’maase) is that the 999 should fail out so that the one who is pushed can become a Gadol. If you teach secular studies to all 1000, none of them will become a Gadol.
(In practice there are quite a few counterexamples, but that is the theory.)
