“but at least they recognize where they should be-no?”
NO- if you’re in shul and not davening that’s ok too? does that count as if you davened with a minyan? i don’t think so. Just being in yeshiva and not learning is wrong! to whom are you showing off?
Yissachar and Zevulin – one works, one learns. what’s the question? someone has to be able to support those who are learning. yes the workers should learn for at least a few hours but not everyone can learn 24/7.
