Rav Moshe re: “bnei yeshiva”
this is an important distinction that is somehow lost in translation. For me personally, it is obvious that someone going into Rabbonus & Chinuch should spend 110% of his time on limud, and maybe another 10% on getting some general knowledge so that he can apply his learning to current life and relate to his students. You don’t need to become a boke in science, but you need to acquire enough worldview to be able to learn later in life.
Now, for the rest of population, we currently have multitudes going to yeshivos (parallel to masses going to college) – which is a good thing in general, but we need also to train them to earn an honest living. They do not need to go to Ivies, but they can go to local/Jewish/online colleges – and the question should be how to make it safe, not whether. For example, use yeshiva classes/CLEP/AP for humanities to avoid indoctrination, do not dorm in strange places, have hevrusas, combine w/ learning (when R Twerski wrote to Steipler whether he can go to Med school, Steipler replied – with daily hevrusa, mussar/chasidus learning, mikva, I think). I believe this is actually happening under the radar, with people using small NJ colleges to pass at lowest requirement level.
