Metrodriver, that’s beautiful in theory, but
a) what kind of part time work?
b) when do they get the training?
c) at that point can they get by on a part time salary?
This is kind of the theory of the learner/earner model, which in its truer form, of the boys already primed for working by the time they were married, could really prolong the learning of many. I know of a professional who was able to pull this off. Yes, he invested a few years of training (happened that he got married late) but he was working half day, learning 2 sedarim till his mid thirties. (I said prolong the learning of many; of course he, and others like him, are still seriously learning even though they work full time now.)
