I will not dispute Rav Shteinman. Secular education includes alot of anti-Jewish ideas (ie in science, psychology etc). Yes, our kids should learn Torah. However, many kids are coming out of the hareidi system HATING to learn, bc they are studying and studying and studying long hours instead of being children. At least the secular system knows how much learning a child can tolerate, and when it’s just too much..
Rav Lazer Yudel Finkel is known for pointing this out. When asked why the Americans learn as well if not better than the Israelis once they get to Bais Medrash, he responded that the Israelis never played when they were young, so they make it up when they get older. The Americans played when they were younger, so they are refreshed and able to learn when they are older.
