This is a hard one: on the one hand it is taught that if Bnei Yisroel were to devote all their time to learning, then the alien nations would support them – but that sounds incredibly idealistic, no? It is also taught that if Bnei Yisroel were to collectively keep two Shabbats in a row, this would bring Moshiach. Also idealistic?
I think this is a matter of bitachon and emunah. Yes, Zvulun was credited with the Torah of Yishcar because of their support, and anyone who is unable to learn can receive credit for that mitzva through direct support of a learner or yeshiva, it is taught what R’ Akiva told his students concerning his wife.
But I think the ideal is for all Yidden to sit and learn and their support would be guaranteed.
Do we merit this reality?
If we do then maybe we will see.
