Shmoolik 1,
I do not want to be motzei shem ra. on anyperson or institution
Then why did you?
but what are the many non students doing in the yeshivos besides smoking and just hanging around why do they not serve or G-d forbid get a job
Whether or not they should serve is a debate among the gedolim (nachal chareidi). But they obviously can’t get a job. What they should be doing is learning. Their bittul Torah is not just bittul Torah, it’s a chillul Hashem. But this is an individual’s shortcoming, it’s not institutional.
