Manage Finances Wisely

Two years ago, my brother in-law lost his job where he worked for like 10 years or so. He and his wife were worried because they have many financial responsibilities that needs to be taken care of. Being the only bread winner with a wife and two kids o support, it was very hard for him to deal with that responsibility. He went looking for job in Durham where they live, but to no avail. I was wondering whether he thought about looking for charlotte jobs in North Carolina. To this day, he is still jobless and they only rely on his wife's part time job as a Social worker. How in the world they manage to pay the mortgage, car payments, utilities, foods, and sending their kids to private schools? Hubby and I couldn't figure that out ourselves. We don't want to ask either for it would offend them. Anyway, some people has a way of managing their finances wisely just like them.
