Life after death part 4.

Older men are likely to be further along in their careers and come into more wealth naturally, through time.
This ticks the same box that vocational superiority at the same age brings.

In addition to the fertility genetic push, younger women being attracted to men who have a bit of mad money to share will reciprocate and find that younger women like them more, and will return the sentiment.

The financially successful woman will enjoy distractions and amenities that are out of reach of men who don't earn as much. This restriction may be noticed and unwelcome. Even at parity, she may be underwhelmed by teh dates he can afford to pay for since two admissions are needed. Even a guy who does earn a bit more may struggle to treat on events the woman can comfortably pay for and underappreciate his sacrifice. This will lead her to enjoy the company of a man making substantially more than she does because he treats her to events she'd hesitate to afford for herself. The novelty will potentially produce experiences she finds unusually rewarding and this can translate to warm feelings about the man who provided the experience. It is not necessarily intentionally materialistic.

Younger or unusually beautiful women may become accustomed to a certain level of amusement and place a priority on wealth. These are traditionally labeled as "high maintenance" women. They vanish if teh money dries up. Well to do women may also be "high maintenance" this way and even if they pair up with less economically secure men, maybe they don't last, and consciously or not, they gravitate towards more affluent men. The arm-candy women demand it, the successful women drift that way out of attrition effect.

As women continue to surpass men financially, some men will even struggle to "go Dutch" and will end up depending on their lady friend to subsidize their participation; full role reversal. This may encourage women to seek out higher earners when finding wealthier or parity partners becomes impractical. Money will continue to weigh strongly when selecting husband candidates.
