There are many people around us, where their income is not enough to manage a family how do you manage your family and economy? There are many people who manage their family very well even though their income is very low in their personal life, how do you manage it?
When you know your income isn't enough to cover the whole needs of your family there are certain needs you'll have to drop and just like in a scale of preference the family only need those things that are very important that you can't do without. Just as @Abu-Naim said you cut the family expenses, there's no need trying to live a stupendous life to impress anyone. You don't choose what you want you allow your income do the choosing. The most reason people are in debt is because they are servicing a lifestyle that is above their paycheck and that's not a kind of lifestyle a family should keep under this economic hardship that's getting worsening by the day.
