Nat. I have no problem with shadchanim getting more money. But in many cases (like a 30 year old marrying someone much older than her) there is no reason why a shadchan would need a major incentive. Your point about the girls ignoring shadcanim’s suggestions may be true in some cases, but most of the time these older girls don’t hear from shadchanim.
apushatayid: This is not just an initiative, it is (as they themselves call it,) a game changer. It puts girls who can’t afford the money at a disadvantage. (Or worse it puts huge pressure on them to pay it to keep the playing field even ith those who can afford it)). Even for those who can afford it, it adds insult to injury that they are paying just to be looked at.
Perhaps asking for volunteers to become shadchanim for those girls who put their names on a list makes more sense.(these people would get paid only if they make a shiduch)
We can create new shadchanim if the current shadchanim find the older shidduch girls too challenging.
(Of course this will inly solve this part of the problem. The shortage of boys needs to be addressed bu bridging the age gap between boys and girls.)
