“I don’t think he’s going to remember his 10% discount after 10 miserable years. I can’t believe anyone would choose a wife because someone is paying him to do so, if so I would check what is wrong with her. “
I believe the one who benefited monetarily from the Nasi project was the Shadchan, not the single. It’s an incentive to the Shadchan to suggest Shidduchim to the boy’s family that are closer in age. No one is forcing a single to marry someone incompatible.
In the pool of available girls, there are girls with specs and personalities similar to those of the boy (tall, short, skinny, fat, loud, quiet, trendy, not trendy, heimish, not heimish, educated, non-educated…), among both younger and older girls. Shadchanim are encouraged to try the older girls first. That’s all.
