One thing is clear -that the only places one finds people sitting and learning Torah for its own sake is in Litvak Yeshivot. It is a curious fact that only people that walk in the path of the Gra have the "heshek" driving desire to learn Torah for no other motive than for itself, not even for the reward of the next world.
{I believe this fact deserves wide spread attention because it is extremely significant. It is obvious to anyone who has stepped for one second into any Litvak Yeshiva, but some people have not and so this fact deserves to be general knowledge.--Even for people like myself who are not up to the level of learning and keeping Torah as we should, at least we ought to know what real authentic Torah is.]
