Cute joke, but that joke is a reflection of a lack of bitachon. The father is a shliach of Hashem to provide money, and if he didn’t do it, somehow the son in law would get money. Except that we can’t rely on a nes, so if there’s no derech hatevah income, he can’t just rely on Hashem. But my point is that in a scenario, due to parental or spousal monetary support, he can learn, there’s no excuse.
