thought about this some more and i think it's just too limiting to go for someone just for money. there are so many things to consider. hygiene, attention/validation, sex, pet allergies, cooking skills, home repair skills, teamwork, speed of text replies, listening skills, their social media exposure, their family drama etc.
people act like they can't be dumped for their allergies or some weird facial expression they make when they're not listening or chosen for sexual reasons beyond anything else.
