Square – do they ask people in shomayim why they weren’t engaged in any of those professions? Chazal say what they ask; if they were honest in whatever they did and if they learned enough Torah. When i go to shomayim, i might have a lot to answer for, but why i wasn’t a radiologist won’t be part of it, this i am sure.
Re, rav miller: his talmidim do not discourage being in kollel while on govt programs nowadays. Rav miller was niftar in 2001; it isn’t a shitah issue so much as a practical one. His overarching opinion however, was that most people should work at some point, and that if you’re in kollel, you really need to spend your time wisely.
He also said that college is like a bathroom; sometimes you need to use it.
