The main reason that Litvak {Lithuanian} yeshivas are important is to improve character. They are as far as intention goes doing the same thing that boy scouts were supposed to be doing before they fell into the dark side. That is it they are not just for learning Torah. This in part is connected with learning Musar. But that is not all it is. It is because there is an awareness that people are not automatically good. They need to be taught good character.
