If you polled 100 women whether they would sign a marriage document in which the man faces no financial consequences, and she faces fifty percent asset seizure, I'd venture to guess roughly 99 of them would say no. Apparently you found the one, congrats are in order. Most Cosmopolitan cities, women who make 3 times as much as a male suitor are rarely willing to even split the drinks tab.
Why would some males not want to pay, if they want the date?
I don't see what you see at all. As a matter of fact, almost without exception, all of the working class people I know are hooked up with somebody. The way you tell it, only the "successful" have a chance in the dating market, because women are all secretly planning to leave and take half.
