Should one leave a job in a restaurant that serves alcohol and pork, given the absence of a financially viable alternative, and is it permissible to pursue a master's degree with accumulated money, even if it requires borrowing a portion to meet basic needs?

It was previously explained that cleaning vessels used for alcohol and pork is forbidden, and is only permissible for one who is in dire necessity. If the questioner is able to undertake another permissible work without significant harm and earn enough from it to suffice him, then he is not allowed to remain in the forbidden work, because he is not in dire necessity. As for the money he earned from his previous work in the restaurant, there is no harm for him in spending from it on himself and his family in a reasonable manner, because he is among those in need.
