GAW-if they don’t learn the proper math and skills to use money wisely in yeshiva then the parents must teach it to them.
In response to the situation you presented about the boy that thinks it will take away from his hasmada, I don’t know if it is wise for one to think that way. He should definitely be consulting his Rebbe. We know full well that the chofetz chaim didn’t think that way……sechel is surely in order here.
000646-Yes, I do understand that there will be those bochurim who will be drawn to a father in law who will help support, and I see the need for that. I know many parents who don’t really have a lot of money but want so badly for their children to be learning in Kollel as long as possible and carefully allocate money to help their children build a beautiful foundation. It’s done in a thought out balanced manner…not for the superfluous and extraneous imagined needs one sees in imbalanced situations.
