Yseribus: Is Rav Shach Litvish enough for you? First of all, before WWII, in Europe, virtually none of the Litvish Yeshivos had any serious secular studies program. All that is American. Secondly, Rav Chaim Segal ZT’L, the Menahel of the High School at Yeshiva Chaim Berlin was once told by Rav Shach ZT’L that if possible, he should not be teaching English studies. In Eretz Yisroel, almost all Chareidi Yeshivos do not have English at that age. Rav Aharon Kotler ZT’L made some kind of commitment not to allow English studies on the HS level in Lakewood. The exact details, and if this was actually a Takanah or merely a preference, is not clear and depends who you ask. In any case, Rabbi Elya Svei, Rosh Yeshiva of Philadelphia and a student of Rav Aharon’s, was asked why he allows English in Philly if Rav Aharon was against it. What difference can there be between the town of Lakewood NJ and Philadelphia PA? Reb Elya answered that he has no choice, and that currently, the Baalei Batim would not send their kids to the Yeshiva except under these circumstances. Is any of this the ideal? No. It is not. Is it justified? The schools say it is, as they have no choice. But the point is not what the Jews do, its what Judaism wants. Everyone agrees that it would be a higher level, a preferable situation if we would indeed not learn English even at the HS level, at least not beyond what is necessary to survive. Nobody claims it is an ideal.
Regarding High School, the only reasons it is allowed is either because education is mandated by State Law (in New York it is until age 17), or simply because if they did not have High School education in the Yeshivas, parents would simply send their kids to worse places to get it.
But it is definitely looked upon not as a l’chatchilah, but rather as something that is annoyingly necessary in the current environment.
Today, there are a small number of High Schools in America – particularly in Lakewood – that do not teach English. Also, many Yeshivos do try to reduce the amount of secular studies as much as possible, through knocking out the last semester of English, and a number of kids are leaving HS early to enter Bais Medrash.
Is Rav Moshe and Rav Ahron Litvish enough for you? Rav Moshe Feinstein ZT’L denounced college in a Teshuva, and in a famous speech delivered to his students, published under the title “The Counsel of the Wicked” (Vaad LeHaromas Keren HaTorah, New York, 1978). There he reiterates that everyone has an obligation to become great in Torah, we should not care so much about Cadillac’s (yes, this was said in the “olden days”), and that learning Torah is what we should be pursuing, not secular stuff. He says in America you do not need college to make a Parnassa, and we should be willing to live on little, not a lot, for the sake of Torah, and that R. Nehuray’s statement of abandoning all skills in favor of Torah applies all that more today that we live in a country where you can make a parnassa without college, with no miracles needed.
There is a tape available in many Seforim stores called “The prohibition to learn in Colleges” (Yiddish), which contains addresses by Rav Moshe Feinstein ZT’L and Rav Aharon Kotler ZT’L condemning college.
