The man you describe does not put much thought into his choice of a life partner. Some do not peer beyond the Barbie looks and, therefore, miss important clues about character.
But let’s be honest here. Are today’s western women really of a high enough quality after a lifetime of feminist propaganda, along with the usual female entitlement mentality, to expect a young guy waste his time and money on trying to find the one that isn’t a nut?
Bigg Red, you have hit the nail on the head.
You reap what you sow. If a many marries primarily in order to have access to sex, he should not be surprised that his wife married primarily to have access to money. Neither one is a particularly admirable motivation. But at least it was workable in the past where women were dependent on men for financial support to raise their children. The tradeoff was fairly equitable.
Now that women have expanded opportunities in the workplace, they are less dependent on a husband for money. Now that men have expanded opportunities for porn, casual sex, and other gratification, they are less dependent on a wife for sex. Couples should think carefully and discuss what it is they expect from a marriage and from each other. Few people will honestly admit what it is, even to themselves.
