We never had so many people in yeshivas and kollelim as we had now. Maybe in the midbar. This is welcome change from 100 years ago, when Chofetz Chaim was calling on Yidden in Poland to teach their kids chumash with Rashi without skipping prokim, form learning groups in shuls, women who can read to read several pages of niddah halochos to those who can’t, and not send kids to anti-religious Jewish schools where they teach stories from Tanach, and suffer being working poor instead of going to far-away countries where they can earn more money.
Still, we are obviously not producing proportional number of Chazon Ishes and Chofetz Chaims, as the small yeshivos of 100 years ago. So, these are obviously different institutions with different goals. Maybe using same name creates confusion in the discussions. Our communities found/decided that it takes 15 years minimum (from pre-K to post-HS yeshiva) or more (with kollel) to make sure our kids are not going OTD and keep enthusiasm for learning, and send their children into the same direction.
