Watching YouTube while snacking, but my mother-in-law's payday loan situation is hopeless

From the daughter-in-law's perspective, she must feel like she's going crazy. It's not just once or twice; she keeps taking out loans, and knowing she's done it again, her family must be having a really hard time. I heard an interview with the husband where he said before they got married, his mother borrowed money from a loan shark using his car as collateral, and when she didn't pay it back, his car was repossessed. After that, she apparently took out loans from 3-4 other places. She borrows small amounts like 800,000 or 1,000,000 won, putting the family in a difficult situation. I don't think there's any solution for a family like this. The loan shark even invited the family to a group chat and posted the mother-in-law's face picture along with the loan agreement, spewing insults. From the son's perspective, he needs to cut ties with his mother, but this is causing severe conflict with his wife, and he's just neglecting the situation. It's frustrating to watch.
