1. I would immediately discard the gender division.
Why, for example, a woman cannot provide for her family, or, for example, both (husband and wife) supported the family on an equal footing? There are no standards, there are all sorts of situations. And the "thesis" - "a man earns and a woman nurses children, cleans the apartment and cooks food" - smells strongly of the Middle Ages
2. The task of ANY family member is to create and bring to the family those assets and values that he can. Someone is money, someone is comfort, someone is high-quality and reasonable management of the family budget, someone is investment, someone is EDUCATION of children (this is very important).
3. What is "permanent income" for you? Working as an employee with a monthly income? Own business ? Investment activities ? Self-employment (folk craft, outsourcing, ....) ?
I would phrase it a little differently. This is if we talk about material wealth and financial independence. The goal of each family member is to generate income, preferably from an active and passive part, and preferably with more than 1 source of income. Everyone - according to their capabilities, and with an understanding of their responsibility.
And the wording "the main goal of a man is to support his family" - as if hints that all the rest are kept women in relation to a man. It is not right
