Oomis, I see you believe that learning Torah “upholds the spiritual health of Klal Yisrael.”
What’s interesting is that it also ensures our physical wellbeing in this world. I’m sure I don’t need to try and prove to you that our existence through two thousand years in Galus, most recently through World War II and through numerous attacks by our enemies in Eretz Yisrael, is totally beyond the bounds of teva as we understand it. Our physical survival depends on Torah as much as our spiritual health does.
The yeshiva bachur staying late in the Bais Medrash to clarify the sugya, may be keeping the neighbors that he doesn’t even know, safe and sound in their beds.
This is not meant to disagree in any way with the rest of your comment!
