Popa, considering the state of Yeshivas nowadays and how many are in dire financial situations, its harming your neighbors when you don’t pay tuition. You are harming the Rebbeim when the schools don’t have enough money to pay them and htey can’t afford to feed their families. At some point, something has to give.
Living off others is not a Torah value. But I agree, if you want to learn long term, you should marry rich. Or a woman with a job that can provide.
