So far, the only Rambam actually quoted here is AGAINST Joseph.
Learning Torah, however, IS an ikkar. Working is like going to the bathroom in Yeshiva- it’s a temporary petur from learning, but it’s not learning.
Kollel is wonderful, and if someone supports you, it’s even more wonderful. but nobody has a chiyuv to support you, and nobody has a chiyuv to go into debt to support you. The extortion that goes on for shidduchim today is ridiculous and lacking menshlachkeit. Learning mitoch oni does wonders for one’s commitment to learning.
