Culture's important because some women don't want to work after marriage so the husband's earning to support them. In some cultures husband & wife are expected to get job to support their life. If married couple's had money they wouldn't care about culture because their life style would be different.
It all depends on the culture isn’t it. In my country, there is a certain tribe I wouldn’t want to mention where the woman technically is the bread winner of the family. This is from an era where they prioritized farm works. The woman gets to go work in their farms, having the husband for support if he wills it and the proceeds is brought home for the family. What usually is the main job of the man here, protection and provision of certain essentials like meat and fish but, that’s from an era from a none far distant time yet, still functional in some rural communities.
Now, we’ve come to a time where their is a need for every able member of the family with the ability to put in work needs to do so to handle the ever worsening economy. It is best to have not just an understanding woman at your side but, a woman that could not only provide but offer logical suggestions to issues of finance.
Well, this wouldn’t matter much if you are truly wealthy.
