"Everything is really simple. Everyone’s contribution to the family (financial, labor, moral) should be the same.
Both must earn. Earn at about the same level. At home, of course, both should work the same way. No division into "male" and "female" work."

Here is fucking. Everyone should invest as much as they can. Do not count "let you wash the dishes and I wash the floors", do not come up with complex efficiency coefficients, but stupidly clutter for the common good. And when both members of the family understand this, the family remains strong for many years. And when one spouse believes that he is a person, not a servant, and tries to sit on the neck of another, the marriage quickly ends in divorce.
Moreover, the principle of honest work does not refute the idea of the division of duties. You just have to go in good faith. At home and at work.
