Marriage is not a business transaction! Marriage should be based on love and mutual understanding and respect. Therefore, the postulation is meaningless and have no place in marriage relationship.
When I was a youngster, I was nestled in a middle-class family and never, never, never had the desire to marry a rich man, exactly cause such a mishap. A cousin of mine did, but riches absolutely weren't her aim. They knew each-other cause job's purposes and he freely chose my cousin, despite his family was against that marriage (my cousin was a low-middle-class woman because my aunt's family is big and in the beginning was counting only on my uncle's salary). My cousin owns a superior education, but unfortunately her degree wasn't enough for her husband's family to compensate the financial gap. In any way, my cousin wasn't a true poor, but his family considered her as a poor (despite low-middle-class doesn't mean poverty). Cause in my opinion we never marry a single person, but we marry his/her whole family too, I would never have been glad to bump into such a mishap. And I preferred by far to marry a man belonging to a poor family, financially very much lower than mine. In any way, these aren't advices: I only acted according to my opinion.
Such a mishap happens when the spouse coming from the impoverished background expects his/her partner to sustain his/her siblings, nephews, nieces, maybe parents also. Worse, to sustain all his/her social environment. It happened to The White Massai (the movie is based on a sad true story). A woman from Switzerland married a very poor Kenyan, coming from a very poor village. Apart from the very different cultural background, many mishaps came when he expected her to sustain his entire village, believing she should take as much money as she wanted from the Swiss bank. Obviously, the business she had opened, in addition considering the corruption of a local policeman who kept on blackmailing the village, ended up in failure. When she returned to Switzerland with her daughter, her finance and Swiss account resulted broken.
