Times are hard in this generation and nobody wants to marry a liability anymore, people who are getting into marriage are looking for partners that can make their lives better. In the old days and traditionally the man goes out to work while the woman manages the home, this is still practiced but most new couples work. Men are finding it quite hard to carry their family responsibilities alone so most of them are looking for industrious women as wives.
In other words, you're saying the old generation where the woman manages the home is a liability?

There are still many men who want to get married and make their wife manages the home, men are feel proud when their wife appreciate everything given by them. The problem of current generation is, most women are arrogant and can't appreciate what given by men when they earn higher than men.
Women that don't bring anything to the table finds it quite difficult to get husbands, they are expected to have a job, a business or profitable skills so that they can support their husbands financially.
It's because they can only give their pussy, but they can't become a good wife, mother, manage money and how to feel enough.
It's the same with men who can only give dick, is there woman want to get married only for a dick? the answer is no, the same to woman who can only give pussy.
